Before I post as a bug, I want to make sure it's not something stupid I am doing wrong.

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.

Any ideas on what this could be?
