Help for Asterisk configurations with video intercom

Hi,

on my PC with Linux I have an application programmed in Python with PJSUA2 used to connect to my video intercom IP.

First I used an Android Application as Sip Server installed on my mobile phone, It words but it is not so comfortable.

Now I’m trying to use Asterisk installed on my PC because much more usable.

I’m not an expert and I followed my tutorial in order to understand the correct way to configure Asterisk. I succeed in making to ring the “virtual phone”on my PC and in opening and closing the call, but I couldn’t “transport” incoming and outcoming audio.

My firs idea was a conflict between the ports, so I installed Asterisk on another PC but the prblem wasn’t solved.

In PJSUA2 report, it seems that audio is closed because not used (?!)

pjsip.conf, extensions.conf, voicemail.conf and Asterisk and PJSUA2 report attached

someone can help me.
thanks

You don’t have any allow lines for your video codec (H264, in this case).

thanks david,
I have place for each endpoint in “pjsip.conf” file
allow=H264
but it still not works.

I recive an error message from PJSUA2

pjsua_media.c .......Skipped
updating media call02:1 (media type=unknown): Unsupported media type
(PJMEDIA_EUNSUPMEDIATYPE)

Where can my mistake be?
thanks

Are you using a really ancient PJSUA, in which case see:

https://trac.pjsip.org/repos/changeset/1689

I also noticed in your original trace that Asterisk said: do not use video, but PJSUA made an offer of video, which looks wrong to me.

tks David,
I’m using the latest PJSUA2 version, but I think that the problem is not in PJSUA2, because the program works with other Sip Server. I belive that some Asterisk parameters (configuration) should be setted but I don’t know witchone.

Moreover when I follow your suggestion (many thanks) to use “allow = ulaw,h264” in any endpoit, something good happens: I can hear some sounds (even with Larsen effect since my PC and the video intercom are near).
BUT after a few seconds (3 sec more or less) sound stops and the following message appears:


`20:52:19.265           sound_port.c  EC suspended because of inactivity`

thanks for your help

As a pedantic point, this issue can only arise when it is interacting with a SIP client. Asterisk acts as both.
