> Have 8845 Cisco video phones setup using chan_sip on asterisk 13 / 16. Video between the phones works perfect, but If one of the phones leaves a message in voicemail, the voicemail system records the video and audio as it should.
> On voicemail playback of this voicemail, the video is very slow, almost in slow motion but the audio is fine.
> Tested the voicemail files using playback and get the same issue.
> I changed the format to just wav to see if that helped… no change  Tested on Asterisk 13 and 16 …. no difference. 
> The phones are set up for ulaw & h264.  Also tested with Linphone for Windows. Linphone to 8845 video works perfectly. Linphone to record a video voicemail works. Playback of video voicemail does not work at all on Linphone.
> I can play back the recorded message from the cisco but again it's slow.
