Dear Colleagues,
I have faced with a strange problem during a new videoconference installation.
The whole solution has two main components:
- UCM/IMP/CMS based infrastructure with jabber clients and conference rooms
- 3rd party call control/register server with SIP and H323 video endpoints
When I call a videoconference endpoint from jabber, the softclient sends 384x216 30fps only (but receives 720p30).
This low resolution appears only between the jabber and video endpoints, every other direction works perfectly:
- CMS room <-> video endpoint 1080p
- CMS room <-> jabber client 720p
- jabber client <-> jabber client 720p
We have only one region with 2048kbps bit rate for video and for immersive calls as well.
Does anybody any idea where can I find the solution?
Thanks,
Laci

Thanks for the response.
I copied from the SIP trace the relevant SDP part of INVITEs and 200 OKs.
1st INVITE from Jabber
a=rtpmap:126 H264/90000
a=fmtp:126 profile-level-id=42E01F;packetization-mode=1;max-fs=3601;max-rcmd-nalu-size=32000;level-asymmetry-allowed=1
a=imageattr:126 recv [x=[32:1:1280],y=[18:1:720],par=1.7778,q=1.00]
a=rtpmap:97 H264/90000
a=fmtp:97 profile-level-id=42E01F;packetization-mode=0;max-fs=3601;level-asymmetry-allowed=1
a=imageattr:97 recv [x=[32:1:1280],y=[18:1:720],par=1.7778,q=1.00]
200 OK from Endpoint
a=rtpmap:126 H264/90000
a=fmtp:126 packetization-mode=1;profile-level-id=428014;max-br=2500;max-mbps=245000;max-fs=8160;max-smbps=245000;max-fps=3000
a=rtpmap:97 H264/90000
a=fmtp:97 packetization-mode=0;profile-level-id=428014;max-br=2500;max-mbps=245000;max-fs=8160;max-smbps=245000;max-fps=3000
2nd INVITE from Jabber
a=rtpmap:126 H264/90000
a=fmtp:126 profile-level-id=42E01F;packetization-mode=1;max-fs=3601;max-rcmd-nalu-size=32000;level-asymmetry-allowed=1
a=rtpmap:111 X-ULPFECUC/90000
a=fmtp:111 max_esel=1420;m=8;max_n=32;FEC_ORDER=FEC_SRTP
200 OK from endpoint
a=rtpmap:126 H264/90000
a=fmtp:126 packetization-mode=1;profile-level-id=428014;max-br=2500;max-mbps=245000;max-fs=8160;max-smbps=245000;max-fps=3000
a=rtpmap:111 x-ulpfecuc/8000
a=fmtp:111 multi_ssrc=1;feedback=0;max_esel=1450;m=8;max_n=64;FEC_ORDER=FEC_SRTP;non_seq=1
Is there any problem with the profile-level-id?
Thanks,
Laszlo
