SIP trunk calls going to voicemail pro, but silence

[evoguy]

I have an issue using vm pro. We have the SIP trunks working fine however when the call covers to voicemail we see the following in the trace

/25/13 9:26:51 AM-127ms Line = 17, Channel = 3, SIP Message = Response, Call Ref = 577, Direction = From Switch, From = number@10.251.0.74, To = number@10.250.14.209, Response = 180 Ringing
4/25/13 9:27:06 AM-122ms Call Ref = 577, Retargeting
4/25/13 9:27:06 AM-125ms Call Ref = 577, Originator State = Incoming Alerting, Type = Trunk, Destination State = Alerting, Type = Mailbox
4/25/13 9:27:06 AM-134ms Line = 17, Channel = 3, SIP Message = Response, Call Ref = 577, Direction = From Switch, From = number@10.251.0.74, To = number@10.250.14.209, Response = 200 Ok
4/25/13 9:27:38 AM-134ms Call Ref = 577, Originator State = Clearing, Type = Trunk, Destination State = Alerting, Type = Mailbox
4/25/13 9:27:38 AM-134ms Call Ref = 577, Disconnect from Originator End

We suspected a codec issue of some sort but there are PRI trunks and it works fine with the PRI trunks. Any help would be appreciated. I dont work on IP office on a daily basis .

You need to make a monitor trace.
If you use SSA then check if it uses a VCM channel and which codec it uses.
Although VMPro runs on a PC/server, it is not IP but TDM.
So PRI works because it does not need a VCM channel but SIP does.



BAZINGA!

I'm not insane, my mother had me tested!

As the SIP trunk works I assume there are VCM channels available.
When having a issue you should always provide:
Type of system with additional hardware
Software versions
monitor trace with additional info

A simple mind delivers great solutions

I recall this was an issue on one version of software. can you tell us what you are running?
