             Summary: SDP negotiation issue
                 Key: ASTERISK-28417
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28417
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/General, pjproject/pjsip
    Affects Versions: 13.26.0
         Environment: Linux
            Reporter: Alan


I compiled Asterisk 13.26.0 with external pjsip 2.6.

Asterisk is in the same network as 2 phones:
extension 11: software phone based on pjproject 2.8
extension 02: hardware phone Grandstream GXV3240

When 11 calls 02, audio works well but the video looks terrible.

extract of SDP from 11 to Asterisk:
m=video 4014 RTP/AVP 97 96
c=IN IP4 10.6.0.254
b=TIAS:256000
a=rtcp:4015 IN IP4 10.6.0.254
a=sendrecv
a=rtpmap:97 H264/90000
a=fmtp:97 profile-level-id=42e01e; packetization-mode=1
a=rtpmap:96 H263-1998/90000
a=fmtp:96 CIF=1;QCIF=1
a=ssrc:1987299971 cname:719547ff01003a20

extract of SDP from Asterisk to 02:
m=video 4014 RTP/AVP 97 96
c=IN IP4 10.6.0.254
b=TIAS:256000
a=rtcp:4015 IN IP4 10.6.0.254
a=sendrecv
a=rtpmap:97 H264/90000
a=fmtp:97 profile-level-id=42e01e; packetization-mode=1
a=rtpmap:96 H263-1998/90000
a=fmtp:96 CIF=1;QCIF=1
a=ssrc:1987299971 cname:719547ff01003a20

extract of SDP from 02 to Asterisk:
m=video 5006 RTP/AVP 99
a=sendrecv
a=rtcp:5007 IN IP4 10.6.0.244
a=rtpmap:99 H264/90000
a=fmtp:99 profile-level-id=42E014; packetization-mode=1
a=content:main
a=label:11

extract of SDP from Asterisk to 11:
m=video 19562 RTP/AVP 97
a=rtpmap:97 H264/90000
a=fmtp:97 packetization-mode=1;profile-level-id=42E01E
a=sendrecv

At this point the profile-level-id changed from 2.0 to 3.0.
Could this be causing the video issue?
