[Opalvoip-user] Error with SIP video call: could not find compatible video format

[Giovani G. <gio...@gm...>]

Hi Guys,

I have a sip number that must receive multiple SIP video calls (you can
think as a server that receives multiple video calls and creates a kind of
video conference).

The first SIP phone calls to the server and selects the correct codec:
h263plus. However, when the second SIP phone call, the server prints a
message "could not find compatible video format" and selects the PCM-16
video format. Thus, the video call does not work correctly, only the audio
is transmitted correctly.

Below I put part of the log output.

Can someone give me a clue on what it is going on here?

Best regards,
