I have 2 IT82R with latest firmware version 82.30.2.517 which are serving an intercom from 2N (2N IP Verso); I'm trying both Direct IP calls and calls via SIP Proxy (asterisk based).
In both the ways (direct IP or via SIP proxy), when a call is from 2N to IT82 I can see the video stream on the IT82 display, both on the preview and during the call itself, but when the call is from IT82 to 2N there is no video on the IT82 display (the audio is OK).
I noticed that IT82 is not using configured parameters in outgoing call setup; on the IT82 web setup page, Account-Advanced, it's set to use the Video Codec H264 with "Codec Payload" = 94, but that is not used.
Here there are 2 capture of the SIP traffic, the first is an incoming call from 2N to IT82 where the video is working good, the second is an outgoing call from IT82 to the 2N, where the video is NOT working.
Code: Select all

As you can see in the second capture, the video codec parameters in the SIP request from IT82 are not as configured in the web page and they are not supported on 2N intercom.
Is there anything I can do fix this issue?
