Not able to get Video between 2 Asterisk Server Trunk setup

Asterisk Asterisk SIP
1

Hi,

I’m trying to configure trunk between tow server for video call which is not working.

Trunk code in sip.conf, in server A and server B is as below.

####Server-A sip.conf at the end of file.
[trunk_two]
type=friend
context=from-trunk
context=default
;nat=no
canreinvite=yes
host=172.16.16.250
insecure=invite
videosupport=yes
;disallow=all
;allow=ulaw
allow=h264
allow=g729
allow=h265
allow=vp8

####Server-B sip.conf at the end of file.

[trunk_one]
type=friend
context=from-trunk
context=default
nat=no
canreinvite=yes
host=172.16.16.21
insecure=invite
videosupport=yes
;disallow=all
;allow=ulaw
allow=h264
allow=g729
allow=h265
allow=vp8

Can some one help me, how to enable video call between two servers.

Start over with chan_pjsip. chan_sip is no longer in the next release of Asterisk. Also you have various settings that don’t gain you anything and make you less secure. Specifically change friend to peer and delete insecure.

Having G.729 as your only audio codec makes no sense, if you are going to use video. The only reason for using it is to save bandwidth, but the video will be the bandwidth hog.

Always start with disalllow=all.

Only one context line wll be used.

As Asterisk cannot transcode video, you would be better off choosing just one video codec.

We’d need the logs to understand what is not working.

Logs really need to be done at verbosity 3 or higher, so that one can see the dialplan.

One party only supports G.711 A-law for audio and the other only supports G.729 for audio, and you don’t have a G.729 codec module loaded and licensed.

Again, the codec is not both loaded and licensed.

As already noted, G.729 is a strange choice if you are using video. It give reduced audio quality and the video will dominate the bandwidth.

G.711 A-Law is the first choice for 6021, so it will be sending A-law, but you don’t have the G.729 codec loaded and licensed.

As already noted, it is a waste of time to try to get this working on chan_sip, as chan_sip is, essentially, dead.

You haven’t provided us with config files for these, and the channel driver or config file is missing for H323.

It looks to me as though H.264 is the only video codec you should be specifying. Everything on a call must use the same one, and the calling party is using H.264.

The device is either not configured, or has not registered.
