[Asterisk-video] H324m outbound videocalls

[ISAAC GONZALEZ GONZALEZ]

Hola Sergio,
I attach the H223 raw data and H245 messages, what should I look for in them? What software can I use to interpret the data?
I send you the attachments sepparately because they are too big to be posted here.

Un saludo, gracias de nuevo
Isaac

Hola Isaac,

In this cas I would blame also your pbx manager.. :)

The mos probable cause of this is an external transcoder or echo 
canceller that is mangling the h223 data.  Check it with H223 raw data 
and H245 messages that should be in /tmp

Un saludo
Sergio

In the h245.log there is only a "terminalCapabilitySet request" sent from the server to the mobile, and no response or more messages are sent between them, so I understand that channel control is not working correctly. Moreover, no H223 streams or media flows are saved in the debug proccess, I think due to the broken H245 control procedure.

>>> I am trying to do outgoing 3G videocalls and playing a 3gp video. To do that I'm using the fontventa software and the 'originate' CLI command. I am using a Digium PRI card (TE 420) and an N70 mobile phone and I have built asterisk + libpri + zaptel + asterisk LLC patch + libpri LLC patch + fontventa software; however I think the LLC patches are not necesary since the call is established using the Bearer Capability field insted the LLC one.
>>> Using old postings of the list I succeeded in stablishing the outgoing video call, but I cannot see any vídeo stream on my mobile phone when mp4play is running. I tried using X-Lite to initiate the video call with the H324m network but the result is the same. No video or audio stream seems to be transferred.
