Hi Zelalem,
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.
Hi all, I wanted to know if there is a mechanism to know if a call is
video call before answering it. I want to perform something if a call
is video, and do another thing if it is audio.
Thank you.
