00:00:06.860 --> 00:00:09.810 align:middle line:90%


00:00:09.810 --> 00:00:12.100 align:middle line:90%
Hello, and welcome to INE.

00:00:12.100 --> 00:00:14.550 align:middle line:84%
Today, in this video, we
would look at section 6, CMS,

00:00:14.550 --> 00:00:17.213 align:middle line:90%
basically, task 6.7.

00:00:17.213 --> 00:00:18.630 align:middle line:84%
Now, here on this
task, it says we

00:00:18.630 --> 00:00:20.790 align:middle line:84%
need to configure
CMS WebRTC to be

00:00:20.790 --> 00:00:23.910 align:middle line:84%
accessible from the
external Candidate PC using

00:00:23.910 --> 00:00:26.430 align:middle line:84%
the browser or the
Cisco Meeting App,

00:00:26.430 --> 00:00:30.120 align:middle line:84%
configure Cisco Expressway-C
to enable the Meeting Server

00:00:30.120 --> 00:00:34.680 align:middle line:84%
proxy, enable TURN services,
and modify the web administrator

00:00:34.680 --> 00:00:38.700 align:middle line:84%
port to 7443 on the
Expressway-E. Now, as you know,

00:00:38.700 --> 00:00:41.070 align:middle line:84%
Expressway-E, by default,
uses the port 443

00:00:41.070 --> 00:00:43.180 align:middle line:90%
for administrator access.

00:00:43.180 --> 00:00:47.790 align:middle line:84%
So if you want to
do TURN services,

00:00:47.790 --> 00:00:50.350 align:middle line:84%
yeah, TURN services
uses the 443 port.

00:00:50.350 --> 00:00:55.290 align:middle line:84%
So we need to change the web
admin or the administrator

00:00:55.290 --> 00:00:58.530 align:middle line:84%
access to the
Expressway-E. We need

00:00:58.530 --> 00:01:01.240 align:middle line:84%
to change that default port
from 443 to some other port.

00:01:01.240 --> 00:01:05.220 align:middle line:84%
And the question states
that we need to use 7443.

00:01:05.220 --> 00:01:09.060 align:middle line:84%
Besides that, it
also states that we

00:01:09.060 --> 00:01:14.130 align:middle line:84%
need to use Postman to send
API call to create the TURN

00:01:14.130 --> 00:01:17.610 align:middle line:84%
services on CMS using
Expressway-Cs inside

00:01:17.610 --> 00:01:20.280 align:middle line:90%
and the outside interfaces.

00:01:20.280 --> 00:01:23.580 align:middle line:84%
We need to log into Cisco
Meeting App using the account

00:01:23.580 --> 00:01:27.000 align:middle line:90%
hq-two@ine.com on Jabber 1 PC.

00:01:27.000 --> 00:01:29.850 align:middle line:84%
We need to log into Cisco
Meeting App using the account

00:01:29.850 --> 00:01:34.320 align:middle line:84%
hq-one@ine.com on
the Candidate PC.

00:01:34.320 --> 00:01:40.470 align:middle line:84%
And your task is complete
when HQ1 and HQ2 can join

00:01:40.470 --> 00:01:43.200 align:middle line:84%
the coSpace "Test
Space" by dialing

00:01:43.200 --> 00:01:48.570 align:middle line:90%
884111111@hq-cms.ine.com.

00:01:48.570 --> 00:01:50.380 align:middle line:84%
Now, if you remember
in the earlier videos,

00:01:50.380 --> 00:01:51.683 align:middle line:90%
we had created our test space.

00:01:51.683 --> 00:01:53.100 align:middle line:84%
And that's the
space that we would

00:01:53.100 --> 00:01:55.230 align:middle line:90%
be using to test this thing.

00:01:55.230 --> 00:01:58.980 align:middle line:84%
Now, Expressway-E has already
been configured for MRA.

00:01:58.980 --> 00:02:00.720 align:middle line:84%
All that has been
pre-done for you.

00:02:00.720 --> 00:02:03.150 align:middle line:84%
So you can directly
start with integrating

00:02:03.150 --> 00:02:06.330 align:middle line:84%
the CMS and your
Expressway, so basically

00:02:06.330 --> 00:02:07.750 align:middle line:90%
creating TURN services.

00:02:07.750 --> 00:02:10.218 align:middle line:90%
So let's go and quickly do this.

00:02:10.218 --> 00:02:11.760 align:middle line:84%
The first thing,
what I'm going to do

00:02:11.760 --> 00:02:17.160 align:middle line:84%
is I will go to my Candidate
PC, which is on the outside.

00:02:17.160 --> 00:02:21.600 align:middle line:84%
And there are a few things that
I would suggest that you do.

00:02:21.600 --> 00:02:24.870 align:middle line:84%
Again, this is only
because your time sync

00:02:24.870 --> 00:02:26.260 align:middle line:90%
is extremely important.

00:02:26.260 --> 00:02:30.330 align:middle line:84%
Your NTP is extremely important
that your Candidate PC's time

00:02:30.330 --> 00:02:31.800 align:middle line:90%
syncs with Expressway.

00:02:31.800 --> 00:02:37.230 align:middle line:84%
And if I look back at
my switch, my switch

00:02:37.230 --> 00:02:40.540 align:middle line:84%
has been pre-configured
as an NDP server.

00:02:40.540 --> 00:02:44.442 align:middle line:84%
So if I look back at my
switch and do a show clock,

00:02:44.442 --> 00:02:45.900 align:middle line:84%
you would see that
the current time

00:02:45.900 --> 00:02:50.140 align:middle line:90%
is 11:29:59, 16th of January.

00:02:50.140 --> 00:02:52.710 align:middle line:84%
So all I have to do is go
back to my Candidate PC.

00:02:52.710 --> 00:02:58.740 align:middle line:84%
And let's go and
access Control Panel.

00:02:58.740 --> 00:03:00.870 align:middle line:84%
That's something that I
would suggest that you do.

00:03:00.870 --> 00:03:03.210 align:middle line:84%
Always ensure that
your time is synced.

00:03:03.210 --> 00:03:04.680 align:middle line:84%
Because if your
time is not synced,

00:03:04.680 --> 00:03:07.530 align:middle line:84%
your Expressway is not
going to allow you to go

00:03:07.530 --> 00:03:08.880 align:middle line:90%
through the TURN services.

00:03:08.880 --> 00:03:11.670 align:middle line:90%
So go to Date and Time.

00:03:11.670 --> 00:03:13.440 align:middle line:90%
And go to Internet Time.

00:03:13.440 --> 00:03:15.990 align:middle line:84%
And make sure you click
on Change Settings

00:03:15.990 --> 00:03:17.670 align:middle line:90%
and click on Update Now.

00:03:17.670 --> 00:03:19.720 align:middle line:84%
So this will just
resync your time.

00:03:19.720 --> 00:03:22.770 align:middle line:84%
So if you see your time now, now
it has synced to your switch.

00:03:22.770 --> 00:03:25.270 align:middle line:90%
It is 11:30 AM.

00:03:25.270 --> 00:03:27.660 align:middle line:90%
Let's do OK, OK.

00:03:27.660 --> 00:03:31.482 align:middle line:84%
And now we can actually go
and configure TURN services.

00:03:31.482 --> 00:03:32.940 align:middle line:84%
So the first thing
that we would do

00:03:32.940 --> 00:03:37.800 align:middle line:84%
is we would log into
our Expressway--

00:03:37.800 --> 00:03:41.970 align:middle line:84%
log into our Expressway-E and
check what's the domain name

00:03:41.970 --> 00:03:45.540 align:middle line:84%
and what's the FQDN
for Expressway-E.

00:03:45.540 --> 00:03:49.560 align:middle line:84%
So if I look back
at my Expressway--

00:03:49.560 --> 00:04:01.360 align:middle line:84%
let's go to Jabber 1 and open up
Expressway-E. And let's log in.

00:04:01.360 --> 00:04:04.780 align:middle line:90%


00:04:04.780 --> 00:04:15.000 align:middle line:84%
So once I log in and go
to System, Administration,

00:04:15.000 --> 00:04:21.149 align:middle line:84%
you would see that my-- first
of all, my system host name

00:04:21.149 --> 00:04:22.440 align:middle line:90%
is coedge.

00:04:22.440 --> 00:04:27.850 align:middle line:84%
And if I go back to System, DNS,
you would see your domain name.

00:04:27.850 --> 00:04:30.060 align:middle line:90%
So your domain name is ine.com.

00:04:30.060 --> 00:04:35.240 align:middle line:84%
So your fully qualified
domain name is coedge.ine.com.

00:04:35.240 --> 00:04:39.420 align:middle line:84%
And the coedge.ine.com
resolves to the WAN IP

00:04:39.420 --> 00:04:41.250 align:middle line:90%
address of my Expressway.

00:04:41.250 --> 00:04:42.750 align:middle line:84%
So the first thing
that I would do

00:04:42.750 --> 00:04:47.490 align:middle line:90%
is go to my local internal DNS.

00:04:47.490 --> 00:04:51.810 align:middle line:84%
The local internal DNS is going
to resolve coedge.ine.com,

00:04:51.810 --> 00:04:55.590 align:middle line:84%
not to Expressway-E. It is
going to resolve to CMS.

00:04:55.590 --> 00:04:57.540 align:middle line:84%
Because what's going
to really happen

00:04:57.540 --> 00:05:01.770 align:middle line:84%
is when the Candidate
PC from outside

00:05:01.770 --> 00:05:04.140 align:middle line:84%
accesses or tries to
log in, it is actually

00:05:04.140 --> 00:05:07.920 align:middle line:84%
going through
Expressway-E. The Candidate

00:05:07.920 --> 00:05:10.920 align:middle line:84%
PC on the outside resolves
to this DNS server,

00:05:10.920 --> 00:05:12.120 align:middle line:90%
which is on the outside.

00:05:12.120 --> 00:05:14.760 align:middle line:84%
The DNS server on
the outside resolves

00:05:14.760 --> 00:05:19.260 align:middle line:84%
coedge.ine.com to Expressway-E's
public IP address.

00:05:19.260 --> 00:05:23.730 align:middle line:84%
And the internal DNS server
will resolve that same FQDN

00:05:23.730 --> 00:05:25.540 align:middle line:90%
to CMS's address.

00:05:25.540 --> 00:05:27.070 align:middle line:90%
So when the packet--

00:05:27.070 --> 00:05:30.150 align:middle line:84%
when the connection
traverses the Expressway-E

00:05:30.150 --> 00:05:32.460 align:middle line:84%
to Expressway-C,
the Expressway-C

00:05:32.460 --> 00:05:33.960 align:middle line:90%
is going to do a proxy.

00:05:33.960 --> 00:05:37.530 align:middle line:84%
And he will look
up at the local DNS

00:05:37.530 --> 00:05:42.252 align:middle line:84%
and resolve the coedge.ine.com
to CMS's address.

00:05:42.252 --> 00:05:43.710 align:middle line:84%
So the first thing
that we would do

00:05:43.710 --> 00:05:47.190 align:middle line:84%
is go to our internal
DNS server and create

00:05:47.190 --> 00:05:52.770 align:middle line:84%
an A record that maps the
WAN FQDN of Expressway-E

00:05:52.770 --> 00:05:54.730 align:middle line:90%
to CMS's address.

00:05:54.730 --> 00:05:58.230 align:middle line:84%
So let's go back to Forward
Lookup, go to ine.com.

00:05:58.230 --> 00:05:59.800 align:middle line:84%
And let's check what
do we have here.

00:05:59.800 --> 00:06:02.200 align:middle line:84%
So I have Expressway-E's
entry here,

00:06:02.200 --> 00:06:05.790 align:middle line:84%
which resolves to the LAN IP
address of my Expressway-E.

00:06:05.790 --> 00:06:10.080 align:middle line:84%
I do not have any entry for the
WAN IP address of Expressway-E.

00:06:10.080 --> 00:06:11.440 align:middle line:90%
In fact, I do have one.

00:06:11.440 --> 00:06:13.920 align:middle line:84%
I have one that resolves
to the WAN IP address

00:06:13.920 --> 00:06:17.220 align:middle line:90%
also on Expressway--

00:06:17.220 --> 00:06:20.050 align:middle line:84%
on my internal DNS server,
which we don't need.

00:06:20.050 --> 00:06:21.730 align:middle line:90%
So I need to go and modify this.

00:06:21.730 --> 00:06:25.800 align:middle line:84%
This will not resolve
to Expressway-E. Only

00:06:25.800 --> 00:06:29.910 align:middle line:84%
the public DNS server resolves
the coedge.ine.com to the WAN

00:06:29.910 --> 00:06:34.050 align:middle line:84%
IP address of Expressway-E.
The internal DNS server will

00:06:34.050 --> 00:06:37.800 align:middle line:84%
resolve the LAN-side
Expressway-E

00:06:37.800 --> 00:06:42.790 align:middle line:84%
and will resolve the public
FQDN to CMS's address.

00:06:42.790 --> 00:06:45.400 align:middle line:84%
So this will change
to CMS's address.

00:06:45.400 --> 00:06:50.600 align:middle line:84%
So if I look at my CMS
address, it is 31--

00:06:50.600 --> 00:06:52.590 align:middle line:90%
11.100.64.31.

00:06:52.590 --> 00:06:56.130 align:middle line:84%
So I'm going to go back to
this coedge and modify this

00:06:56.130 --> 00:07:02.110 align:middle line:84%
to 11.100.64.31, which
is CMS's address.

00:07:02.110 --> 00:07:06.150 align:middle line:84%
So now coedge.ine.com in
the internal DNS server

00:07:06.150 --> 00:07:07.830 align:middle line:90%
resolves to CMS.

00:07:07.830 --> 00:07:11.040 align:middle line:84%
Coedge.ine.com on the
external DNS server

00:07:11.040 --> 00:07:14.110 align:middle line:84%
resolves to Expressway-E's
WAN IP address.

00:07:14.110 --> 00:07:16.350 align:middle line:90%
That's the first thing we do.

00:07:16.350 --> 00:07:19.350 align:middle line:84%
Once we've done this, the
next thing I'm going to go

00:07:19.350 --> 00:07:24.310 align:middle line:90%
is go back to my Jabber machine.

00:07:24.310 --> 00:07:29.130 align:middle line:84%
And let's go back to
my Expressway-E. Let's

00:07:29.130 --> 00:07:39.700 align:middle line:84%
also open up Expressway-C. So
once I log into Expressway-C,

00:07:39.700 --> 00:07:45.520 align:middle line:84%
I will now go and ensure first
that I have a DNS server.

00:07:45.520 --> 00:07:48.370 align:middle line:84%
The Expressway-C resolves
to the internal DNS

00:07:48.370 --> 00:07:50.500 align:middle line:90%
server, which is there.

00:07:50.500 --> 00:07:53.950 align:middle line:84%
Next thing that I would do is
go to Configuration, Unified

00:07:53.950 --> 00:07:56.320 align:middle line:84%
Communication, go to
Cisco Meeting Server,

00:07:56.320 --> 00:07:59.530 align:middle line:84%
and enable proxy services
so that Expressway-C

00:07:59.530 --> 00:08:04.030 align:middle line:90%
does proxy for CMS.

00:08:04.030 --> 00:08:08.320 align:middle line:84%
So here, I would enable
Meeting Server Web Proxy.

00:08:08.320 --> 00:08:15.206 align:middle line:84%
And the URL or the URI that I
would give is coedge.ine.com.

00:08:15.206 --> 00:08:19.360 align:middle line:84%
So you see now when
Expressway-C gets that request,

00:08:19.360 --> 00:08:21.700 align:middle line:84%
he sees that the web
proxy is enabled.

00:08:21.700 --> 00:08:24.790 align:middle line:84%
And coedge.ine.com, using
the internal DNS server,

00:08:24.790 --> 00:08:25.970 align:middle line:90%
resolves to CMS.

00:08:25.970 --> 00:08:28.930 align:middle line:90%
So he is going to proxy to CMS.

00:08:28.930 --> 00:08:29.815 align:middle line:90%
Let's save this.

00:08:29.815 --> 00:08:36.520 align:middle line:90%


00:08:36.520 --> 00:08:40.870 align:middle line:84%
Once I save this, now I
would go back to Expressway-E

00:08:40.870 --> 00:08:43.000 align:middle line:90%
and enable TURN services.

00:08:43.000 --> 00:08:45.130 align:middle line:84%
To enable TURN services,
the first thing we do

00:08:45.130 --> 00:08:52.080 align:middle line:84%
is go to Configuration,
and go to Traversal,

00:08:52.080 --> 00:08:53.820 align:middle line:90%
and enable TURN services.

00:08:53.820 --> 00:09:00.950 align:middle line:84%
This is on
Expressway-E. So all I

00:09:00.950 --> 00:09:04.520 align:middle line:84%
do is enable the TURN
services, set this to On.

00:09:04.520 --> 00:09:06.980 align:middle line:84%
I don't have to
do anything else.

00:09:06.980 --> 00:09:09.200 align:middle line:84%
Only the username
is going to change.

00:09:09.200 --> 00:09:12.560 align:middle line:84%
The username is going
to be administrator

00:09:12.560 --> 00:09:16.970 align:middle line:84%
because that's the account that
we're using for communication--

00:09:16.970 --> 00:09:20.630 align:middle line:84%
for the traversal zone between
Expressway-C and Expressway-E.

00:09:20.630 --> 00:09:23.280 align:middle line:90%
Let's save that.

00:09:23.280 --> 00:09:29.520 align:middle line:84%
If you actually go back to
Configuration, Authentication,

00:09:29.520 --> 00:09:32.010 align:middle line:84%
and Local Database,
you would see

00:09:32.010 --> 00:09:34.020 align:middle line:84%
that I'm using
administrator account

00:09:34.020 --> 00:09:37.380 align:middle line:84%
for my traversal zone between
Expressway-C and Expressway-E.

00:09:37.380 --> 00:09:40.890 align:middle line:84%
So going back to Configuration,
Traversal, TURN, all I do

00:09:40.890 --> 00:09:42.840 align:middle line:90%
is turn this service on.

00:09:42.840 --> 00:09:45.180 align:middle line:84%
And make sure you put the
correct username, which

00:09:45.180 --> 00:09:46.440 align:middle line:90%
is administrator.

00:09:46.440 --> 00:09:48.450 align:middle line:90%
Let's save this.

00:09:48.450 --> 00:09:51.670 align:middle line:84%
The next thing that I would do
is-- because the TURN services

00:09:51.670 --> 00:09:54.970 align:middle line:84%
is going to use the port
443, and I am currently

00:09:54.970 --> 00:09:59.080 align:middle line:84%
accessing my GUI of
Expressway-E using the port 443,

00:09:59.080 --> 00:10:02.437 align:middle line:84%
I need to change my
port to some other port.

00:10:02.437 --> 00:10:04.270 align:middle line:84%
So as per the question,
it says that we need

00:10:04.270 --> 00:10:07.240 align:middle line:90%
to change that port to 7443.

00:10:07.240 --> 00:10:13.280 align:middle line:84%
So go to System,
Administration, and scroll down.

00:10:13.280 --> 00:10:17.790 align:middle line:90%


00:10:17.790 --> 00:10:20.295 align:middle line:84%
Should be somewhere
here at the bottom.

00:10:20.295 --> 00:10:23.950 align:middle line:90%


00:10:23.950 --> 00:10:27.190 align:middle line:84%
So if you see here,
web service over HTTPS.

00:10:27.190 --> 00:10:29.640 align:middle line:84%
And if you look at the
web administrator port,

00:10:29.640 --> 00:10:31.080 align:middle line:90%
default is 443.

00:10:31.080 --> 00:10:34.170 align:middle line:90%
Let's change that to 7443.

00:10:34.170 --> 00:10:37.050 align:middle line:84%
So once I save
this, I would not be

00:10:37.050 --> 00:10:40.050 align:middle line:84%
able to access the
GUI of Expressway-E

00:10:40.050 --> 00:10:42.002 align:middle line:90%
using the port 443.

00:10:42.002 --> 00:10:42.960 align:middle line:90%
It's not going to work.

00:10:42.960 --> 00:10:44.970 align:middle line:84%
I have to restart
my Expressway-E.

00:10:44.970 --> 00:10:46.392 align:middle line:90%
So let's quickly do that.

00:10:46.392 --> 00:10:47.850 align:middle line:84%
I would not be able
to access that.

00:10:47.850 --> 00:10:51.600 align:middle line:84%
I have to now access my GUI
of Expressway-E on 7443.

00:10:51.600 --> 00:10:55.530 align:middle line:84%
And TURN services is
going to use the port 443.

00:10:55.530 --> 00:11:00.540 align:middle line:84%
The last thing that I need to do
is enable TURN services on CMS.

00:11:00.540 --> 00:11:03.000 align:middle line:84%
Now, that can only
be done through API.

00:11:03.000 --> 00:11:06.060 align:middle line:84%
You cannot really do it
through the GUI of CMS.

00:11:06.060 --> 00:11:08.160 align:middle line:90%
So let's quickly restart this.

00:11:08.160 --> 00:11:19.570 align:middle line:90%


00:11:19.570 --> 00:11:20.890 align:middle line:90%
Let's go to--

00:11:20.890 --> 00:11:24.370 align:middle line:90%


00:11:24.370 --> 00:11:26.380 align:middle line:84%
Seems like I've
lost my connection.

00:11:26.380 --> 00:11:28.900 align:middle line:90%


00:11:28.900 --> 00:11:30.716 align:middle line:90%
Reconnect.

00:11:30.716 --> 00:11:32.000 align:middle line:90%
OK, let's quickly restart.

00:11:32.000 --> 00:11:38.940 align:middle line:90%


00:11:38.940 --> 00:11:43.910 align:middle line:84%
And now let's go
to the API Postman.

00:11:43.910 --> 00:11:45.860 align:middle line:90%
And let's close all of this.

00:11:45.860 --> 00:11:46.870 align:middle line:90%
We don't need this.

00:11:46.870 --> 00:11:51.080 align:middle line:90%


00:11:51.080 --> 00:11:52.050 align:middle line:90%
We don't need this.

00:11:52.050 --> 00:11:59.460 align:middle line:90%


00:11:59.460 --> 00:12:03.350 align:middle line:84%
And let's create--
let's connect to CMS.

00:12:03.350 --> 00:12:06.740 align:middle line:84%
Now, again, CMS is connecting to
port 445, as per earlier task.

00:12:06.740 --> 00:12:08.630 align:middle line:84%
We had changed the
web admin port to 445

00:12:08.630 --> 00:12:11.000 align:middle line:90%
because WebRTC was using 443.

00:12:11.000 --> 00:12:15.080 align:middle line:84%
So all I would do is
change this to POST.

00:12:15.080 --> 00:12:24.710 align:middle line:84%
And here, I would change
this URL to https://hq-cms.i

00:12:24.710 --> 00:12:37.590 align:middle line:90%
ne.com:445/api/v1/turnservers.

00:12:37.590 --> 00:12:38.860 align:middle line:90%
Go to Body.

00:12:38.860 --> 00:12:41.650 align:middle line:84%
And here is where we will
specify a few things.

00:12:41.650 --> 00:12:45.430 align:middle line:84%
The first thing is going
to be server address.

00:12:45.430 --> 00:12:48.090 align:middle line:84%
This is going to be
the LAN-side IP address

00:12:48.090 --> 00:12:55.740 align:middle line:84%
of your Expressway-E,
which is 11.100.64.21.

00:12:55.740 --> 00:12:58.000 align:middle line:84%
Then I would give
the client address.

00:12:58.000 --> 00:13:00.510 align:middle line:90%


00:13:00.510 --> 00:13:03.540 align:middle line:84%
This would be the WAN-side IP
address of your Expressway-E,

00:13:03.540 --> 00:13:08.410 align:middle line:90%
which is 157.26.1.21.

00:13:08.410 --> 00:13:12.220 align:middle line:84%
Next I would give is
the username, which

00:13:12.220 --> 00:13:14.080 align:middle line:90%
is going to be administrator.

00:13:14.080 --> 00:13:16.610 align:middle line:90%


00:13:16.610 --> 00:13:20.290 align:middle line:84%
Then I would give
the password, which

00:13:20.290 --> 00:13:25.750 align:middle line:84%
is going to be C1sc0123!,
where C was uppercase.

00:13:25.750 --> 00:13:28.472 align:middle line:84%
And the last I would
give is-- in fact,

00:13:28.472 --> 00:13:30.430 align:middle line:84%
there are two more things
that we need to give.

00:13:30.430 --> 00:13:34.750 align:middle line:84%
One is the port
number which CMS is

00:13:34.750 --> 00:13:38.380 align:middle line:84%
going to use for TURN services,
which is going to be 3478.

00:13:38.380 --> 00:13:40.690 align:middle line:84%
And then the type is
going to be Expressway.

00:13:40.690 --> 00:13:42.700 align:middle line:84%
So we are basically
traversing Expressway.

00:13:42.700 --> 00:13:57.040 align:middle line:84%
So TCP port number override
is going to be 3478.

00:13:57.040 --> 00:14:03.040 align:middle line:84%
And the type is going
to be Expressway.

00:14:03.040 --> 00:14:03.620 align:middle line:90%
That's it.

00:14:03.620 --> 00:14:05.200 align:middle line:90%
That's all we need to do.

00:14:05.200 --> 00:14:07.060 align:middle line:90%
And do a Send.

00:14:07.060 --> 00:14:10.750 align:middle line:84%
This would enable
TURN services on CMS.

00:14:10.750 --> 00:14:12.010 align:middle line:90%
Let's do what we wanted.

00:14:12.010 --> 00:14:13.945 align:middle line:90%
And let's do a GET.

00:14:13.945 --> 00:14:17.451 align:middle line:90%


00:14:17.451 --> 00:14:19.730 align:middle line:84%
OK, so TURN services
has been turned on,

00:14:19.730 --> 00:14:21.650 align:middle line:84%
where we've defined
what is the LAN-side IP

00:14:21.650 --> 00:14:24.140 align:middle line:84%
address of my Expressway-E,
what is the WAN-side IP

00:14:24.140 --> 00:14:27.802 align:middle line:84%
address of Expressway-E, what is
the port number, the username,

00:14:27.802 --> 00:14:30.260 align:middle line:84%
the password, and what type of
connection it's going to be.

00:14:30.260 --> 00:14:32.130 align:middle line:84%
It's going to be
through Expressway.

00:14:32.130 --> 00:14:33.227 align:middle line:90%
So that's it.

00:14:33.227 --> 00:14:34.310 align:middle line:90%
All we need to do is that.

00:14:34.310 --> 00:14:37.940 align:middle line:84%
Now let's go back to-- let's,
in fact, minimize this,

00:14:37.940 --> 00:14:39.170 align:middle line:90%
go back to--

00:14:39.170 --> 00:14:42.080 align:middle line:84%
I would not be able to access
my Expressway-E on this port.

00:14:42.080 --> 00:14:47.810 align:middle line:84%
We would have to go
to 7443, so :7443

00:14:47.810 --> 00:14:51.860 align:middle line:84%
to access Expressway-E,
which you-- which we can.

00:14:51.860 --> 00:14:58.690 align:middle line:90%


00:14:58.690 --> 00:15:03.660 align:middle line:84%
So Expressway-E is up and
running on port 7443 now.

00:15:03.660 --> 00:15:06.990 align:middle line:84%
Let's now go to the
Cisco Meeting App.

00:15:06.990 --> 00:15:08.520 align:middle line:84%
As per the question,
we are supposed

00:15:08.520 --> 00:15:13.680 align:middle line:84%
to log in to Cisco
Meeting App on Jabber 1

00:15:13.680 --> 00:15:18.040 align:middle line:84%
from HQ user 2, which
I'm already logged in.

00:15:18.040 --> 00:15:26.330 align:middle line:84%
Let's go to Candidate PC
and go to Cisco Meeting App.

00:15:26.330 --> 00:15:30.010 align:middle line:90%
Or we can even use the browser.

00:15:30.010 --> 00:15:32.340 align:middle line:90%
Let's go to--

00:15:32.340 --> 00:15:36.660 align:middle line:84%
I believe this machine does
not have the Cisco Meeting

00:15:36.660 --> 00:15:37.770 align:middle line:90%
App installed.

00:15:37.770 --> 00:15:39.225 align:middle line:90%
But we can use the browser.

00:15:39.225 --> 00:15:40.350 align:middle line:90%
So let's go to the browser.

00:15:40.350 --> 00:15:51.060 align:middle line:90%


00:15:51.060 --> 00:15:58.311 align:middle line:84%
And here, I would type
https://coedge.ine.com.

00:15:58.311 --> 00:16:02.580 align:middle line:84%
Now, this is resolving by
the external DNS server

00:16:02.580 --> 00:16:06.330 align:middle line:84%
to Expressway-E's
WAN IP address.

00:16:06.330 --> 00:16:10.860 align:middle line:84%
And that 443 is going to use
the traversal services to go

00:16:10.860 --> 00:16:13.440 align:middle line:84%
to Expressway-C. And
Expressway-C is going to do

00:16:13.440 --> 00:16:15.030 align:middle line:90%
proxy to--

00:16:15.030 --> 00:16:18.450 align:middle line:84%
using the internal DNS server
that resolves coedge.ine.com

00:16:18.450 --> 00:16:19.300 align:middle line:90%
to CMS.

00:16:19.300 --> 00:16:22.440 align:middle line:84%
So I should see the Cisco
Meeting App opening up.

00:16:22.440 --> 00:16:23.250 align:middle line:90%
Let's go and check.

00:16:23.250 --> 00:16:26.040 align:middle line:90%


00:16:26.040 --> 00:16:28.310 align:middle line:84%
So if my TURN
services are running,

00:16:28.310 --> 00:16:30.410 align:middle line:84%
I should see the Cisco
Meeting App coming up.

00:16:30.410 --> 00:16:32.990 align:middle line:84%
And I should be able to
log in hq-one@ine.com.

00:16:32.990 --> 00:16:35.690 align:middle line:90%


00:16:35.690 --> 00:16:42.770 align:middle line:90%
And the password was C1sc0123!

00:16:42.770 --> 00:16:45.470 align:middle line:84%
And I'm able to log
in, which basically

00:16:45.470 --> 00:16:49.760 align:middle line:84%
means that now HQ1 is logged
in from the Candidate PC.

00:16:49.760 --> 00:16:54.260 align:middle line:84%
HQ2 is logged in from the
internal PC, which is Jabber 1.

00:16:54.260 --> 00:16:58.220 align:middle line:84%
They both should be able to join
the meeting space by dialing

00:16:58.220 --> 00:17:06.230 align:middle line:90%
884111111@hq-cms.ine.com.

00:17:06.230 --> 00:17:09.970 align:middle line:90%
Let's call into the space.

00:17:09.970 --> 00:17:12.190 align:middle line:90%
So HQ1 has joined in.

00:17:12.190 --> 00:17:16.630 align:middle line:84%
Let's join from Jabber
1 by going to Meet,

00:17:16.630 --> 00:17:28.620 align:middle line:84%
884111111@hq-cms.ine.com,
and call into the space.

00:17:28.620 --> 00:17:32.420 align:middle line:84%
And if you see now,
they-- both the users

00:17:32.420 --> 00:17:35.600 align:middle line:84%
are logged into the
Cisco Meeting App.

00:17:35.600 --> 00:17:38.480 align:middle line:84%
And because I also have
chat services enabled

00:17:38.480 --> 00:17:41.000 align:middle line:84%
from the earlier video, I
should be able to, in fact,

00:17:41.000 --> 00:17:45.570 align:middle line:84%
send chat also-- chat
messages also between them.

00:17:45.570 --> 00:17:58.550 align:middle line:84%
So let's say if I do hi, and
let's go back here to Jabber 1

00:17:58.550 --> 00:17:59.780 align:middle line:90%
and check chat.

00:17:59.780 --> 00:18:02.570 align:middle line:84%
He has received
HQ1's hi message.

00:18:02.570 --> 00:18:04.050 align:middle line:90%
And they both are logged in.

00:18:04.050 --> 00:18:07.490 align:middle line:84%
So with this, we've basically
enabled TURN services.

00:18:07.490 --> 00:18:10.610 align:middle line:84%
And now all users can
log in internally.

00:18:10.610 --> 00:18:12.530 align:middle line:90%
They can log in from outside.

00:18:12.530 --> 00:18:14.780 align:middle line:84%
All they have to do
is go to the browser

00:18:14.780 --> 00:18:21.650 align:middle line:84%
or use the Cisco Meeting App
to log in and chat with users

00:18:21.650 --> 00:18:23.870 align:middle line:84%
or connect with users
or join meetings.

00:18:23.870 --> 00:18:26.090 align:middle line:84%
With this, we've
completed our task.

00:18:26.090 --> 00:18:27.920 align:middle line:84%
I hope this video was
informative to you.

00:18:27.920 --> 00:18:30.500 align:middle line:90%
And thank you for watching.

00:18:30.500 --> 00:18:31.000 align:middle line:90%
