Video didn't work from the first time

HI!
I try to make video call, but I cant =(

Step 1: Make a call between two users (User1, User2)
Step 2: I try to switch to a video call on User1, but nothing happens.
I try again. nothing happens.
*Step 3: But if after this!!! I’ll try to switch to the video call on another user(User2) I did it. :confused:

Why “Video flag: False” if I set “videosupport=yes”??? :confused:
But after few moments I saw in log " chan_sip.c:13054 add_sdp: ** Our capability: (gsm|ulaw|g722) Video flag: True" Why? :confused: I don’t understand.

I found path with adding this functional: lists.digium.com/pipermail/aster … 49150.html

I understand that the case in the settings, but did’t know what to do. :frowning:

Please Help
Thank you!

I found this issue: http://lists.digium.com/pipermail/svn-commits/2011-May/066565.html
I think this is my situation.
and this bug: https://issues.asterisk.org/jira/browse/ASTERISK-14139 is very similar to my case.

Please help to understand how to fix it.
Thank you.

That bug report says it was fixed in a version that is now obsolete. Either you are using an even more obsolete version, or it is a different bug, or a regression.
