FreePBX 14 + Asterisk 13 - i have added the cisco-usecallmanager-patch have soft keys working - more or less everything i need is there including conference - hold - forward - speed dials - etc etc. I have limited the extensions to “alaw&gsm&g722&g729&h264” which they all do support (i have also tried with no codec restrictions) - i have h264 in the chan_sip setup (not using pjsip) - the video is working on the handsets as i can “self view" fine - i am using bria 5 soft phone to test this with.
I can start a video call on the CP-8941 to Bria 5 - and both video and audio work fine - when i call the CP-8941 from Bria 5 there is no video and i see the following in the console. (98 is Bria and 105 is CP-8941)

[2017-08-31 11:17:36] WARNING[14713][C-0000001f]: res_rtp_asterisk.c:4960 ast_rtp_read: RTP Read too short
I am currently on SIP8941_8945.9-3-4-17 firmware on the handsets - i previously took it to SIP894x.9-4-2SR3-1 - which crashed the handsets soon after i saw the “ RTP Read too short message” on the console. (identical to this post http://eng.sysadmins.ru/post11804369.html)
If anyone has any pointers to help me chase this down - i have ssh access to handsets - counterpath are involved with troubleshooting it from the Bria 5 side of things - the CP-8941 is EOL from cisco and does not seem to be to popular so not getting too much info from the community.
