[asterisk-bugs] [JIRA] (ASTERISK-21432) Video isn't negotiated when endpoint switches to video on an established SIP to SIP call

    [ https://issues.asterisk.org/jira/browse/ASTERISK-21432?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=206328#comment-206328 ] 

Rusty Newton commented on ASTERISK-21432:
-----------------------------------------

Thanks.

It looks like for some reason, Asterisk possibly thinks the other leg of the call is not capable of video and so it appropriately rejects video on the one leg.

Can you provide the output of "sip show peer <name>" on both peers before the test call where it fails?

Can you also provide a pcap that includes both legs of the call to make this it easier to correlate events on both sides of the call with what is happening in the Asterisk log?

Also, the log file needs to preferably be the same log for the call in the pcap, so that that call-id's and such match up for easier debugging.

> How to reproduce:
> Step 1: Start a conversation between users (User 1, User 2)
> Step 2: Try to switch to a video call (User 1)
> Video does not start.
> I Get this string in log:
> "chan_sip.c:13001 add_sdp: This call needs video offers, but caller probably did not offer it!"
> *If after Step 2 I try to start video on User 2 it is work fine.
> **If I do video call at start, it is work fine.
> I think that it is similar to the bug: ASTERISK-14139
