Posted: Wed May 13, 2009 9:46 am Post subject: [Asterisk-video] How to know if video call is comming?
Thank you Borja for your prompt response. But I think I have still some questions. I am using Asterisk 1.4.21 version. So, what is the patch (where can I get it) for this particular version. BTW, I am also using the app_mp4 application. The other thing, does the CHANNEL function (that you mentioned) tell me if the call if video or audio? I mean I was expecting a return value that I can use for the GOTOIF function in extensions.conf file to go to a particular place if the call is video or audio. Please elaborate on this. Particularly, I don't understand the Traces from PRI section. I don't use ISDN at the moment.
Yes that is possible.
You have a signaling information in the SETUP packet (in case of ISDN,
you have a similar data in SS7) :
Traces from PRI :
< Bearer Capability (len= 5) [ Ext: 1 Q.931 Std: 0 Info transfer
capability: Unrestricted digital information (8)
< Ext: 1 Trans mode/rate: 64kbps,
circuit-mode (16)
< User information layer 1: H.223/H.245
Multimedia (38)
You will probably need to patch your Asterisk to be able to differe the
2 calls (audio and video).
Normally, after patching the Asterisk you will have an Asterisk Function
called CHANNEL(transfercapability) to get and set the corresponding
Signaling information.

The patch is only for the ISDN Bearer Capability....
For SIP you not need to touch your Asterisk sources.
