Thanks Mike for answer, quite strange that freeswitch always answer with b=AS:1024 for video stream. Let me describe Invite from UA (Grandstream gvc3200) SDP: v=0 o=ipod7 8000 8000 IN IP4 77.120.9.98 s=SIP Call c=IN IP4 77.120.9.98 b=AS:1312 t=0 0 m=audio 5004 RTP/AVP 0 8 9 104 123 101 b=TIAS:64000 a=sendrecv a=rtpmap:0 PCMU/8000 a=ptime:20 a=rtpmap:8 PCMA/8000 a=rtpmap:9 G722/8000 a=rtpmap:104 G7221/16000 a=fmtp:104 bitrate=32000 a=rtpmap:123 opus/48000/2 a=fmtp:123 useinbandfec=1; sprop-maxcapturerate=16000; stereo=0; sprop-stereo=0 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 m=video 5006 RTP/AVP 99 b=TIAS:1024000 a=sendrecv a=rtpmap:99 H264/90000 a=fmtp:99 profile-level-id=42801F; packetization-mode=1 a=framerate:15 a=content:main a=label:11 FS respond part: v=0 o=FreeSWITCH 1458296997 1458296998 IN IP4 77.121.1.26 s=FreeSWITCH c=IN IP4 77.121.1.26 t=0 0 m=audio 26504 RTP/AVP 0 101 a=rtpmap:0 PCMU/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 m=video 31298 RTP/AVP 99 b=AS:1024 a=rtpmap:99 H264/90000 What really confusing me are b=AS:1024 for Video rtp stream and absent a=fmtp:99 profile-level-id=42801F; packetization-mode=1 in freeswitch answer SDP. Why I`m interesting because my device always starts with video resolution 176x144. I tried with asterisk and it`s respond part looks like this for video: a=fmtp:99 profile-level-id=428028 and device starts to send 1920x1080. Now I`m using Freeswitch Version 1.6.6 -13-d2d0b32 64bit from stable repo. On Wed, Mar 16, 2016 at 9:17 PM, Michael Jerris <mike@jerris.com> wrote:
Its only used in mod_conference, and I believe it will be adjusted via rtcp.

Hi, community! In wiki page https://freeswitch.org/confluence/display/FREESWITCH/mod_conference I found parameter for conf room: video-codec-bandwidth . It will be used as SDP respond part as a Bandwidth ("b=") from Freeswitch ?
