[asterisk-bugs] [JIRA] (ASTERISK-13145) [patch] Presence subscription on Cisco SIP phone needs special Cisco-styled XML

[Gareth Palmer (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-13145?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=252585#comment-252585 ] 

Gareth Palmer commented on ASTERISK-13145:
------------------------------------------

The patch doesn't make any changes to RTP payload type handling.

When a SIP peer with cisco_usecallmanager=yes registers with Asterisk a Cisco-specific keyword in the Supported header is sent to the phone indicating the available feature level. This is causing your DX50 to offer multiple H264 streams. chan_sip always uses the first valid one, that may not be the same behaviour as CUCM.

The profile-level-id and and packetization-mode are different for the '97' and '100' streams, does the device calling the DX50 support those options? If not, then process_sdp_a_video would need to be modified to ignore those a= lines.
