Need help with a voicemail bug - Asterisk / Asterisk Support - Asterisk Community
We made another small change in
and I think it is working now as best as we can get it. During testing, it is quite clear that the endpoints/phones are all expecting a handshake/codec negotiation when retrieving video voicemails from the Asterisk voicemail system. Since that system does no such codec negotiation, the videophone endpoints vary widely in what they can display.
The testing I have done has been with Linphone, MicroSIP, Cisco CP-8845 and Cisco CP-8941 phones. When these phones send video to the voicemail system they have a preset default for the resolution and just dump the video file. When they retrieve voicemails that have video in general, unless the resolution matches some other default the phone is expecting, they don’t play the video. So the upshot is if you record a voicemail with 1 model phone and retrieve it with another, it may or may not play.
It is a very simple correction, and I believe it basically puts Asterisk back to the same functionality that Asterisk version 12 had with video voicemails.
The big problem with uncorrected Asterisk as I’ve mentioned in the PR is video voicemails will hang since Asterisk loses sync between the video and audio.
I’d really appreciate it if anyone setting up a new system from a build would test this considering there’s just been new releases last week. I know videophones are a rare breed nowadays.
