Hello Paolo!
Thank you for your response! I very appreciate it!
The full problem is:
I try to integrate third-party SIP Device (Mobotix T24), CUCM and cisco ip phone 8945. I've registered Mobotix T24 on CUCM as third-party SIP device (advanced) and also I've registered cisco ip phone 8945 as SIP device.
When I call from any endpoint (Mobotix T24 or cisco phone 8945) I can establish just audio call between t24 and phone 8945. When I check call status on cisco phone I see it's receiving video streem with resolution 352x288 but the video never ever displays on cisco phone 8945.
I checked logs from CUCM and I see that third party-device advertise video with rtp payload type - 103 98

I have no way to change rtp payload type on the third-party device.
May be it is possible to change payload type on the side of CUCM for example using SIP Normalization Scrip?
Also logs from CUCM in attachment.
Thank you in advance!
