Tom Waterman Posted April 21, 2010 Report Share Posted April 21, 2010 Hello, I finally have UM working but I have one user whose voicemails get cut off after 9 seconds, but only his extension. Is there a way to adjust the gain from the pbx to exchange. I can't think of any other reason why this would happen. Thank you. Quote Link to comment Share on other sites More sharing options...

Is there a way to adjust the gain from the pbx to exchange. I can't think of any other reason why this would happen. The PBX never changes the gain; and there is no option to do that. You should fight gain problems at the root. Maybe that extension has the microphone volume completely out of range. Or even a bad microphone. If it is really a gain problem. A good way to compare gain is to have several phones in a conference room and let them speak one after each other (ideally having the same person on the different devices).

I don't think it is a gain issue at all. The trunk between pbxnsip and Exchange 2007 works for everyone but this one extension. When people go to leave him a voicemail it cuts out after about 9 seconds. The only thing I can find on Microsoft's site talks about the gain being to low and Exchange diconnecting the call because it thinks the call is done. Oh well. I'll do some more research but this is not a PBXnSIP issue. Tom Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted April 22, 2010 Report Share Posted April 22, 2010 If it only happens with one specific phone, then there must be something special about it. Mabe it is the only phone which is behind a special firewall, or is has a different firmware, or maybe you just need to factor reset it and re-provision it.

After a little more investigation it turns out this is happening on all voicemails for all extensions. Theuy get 9 seconds of voicemail and then the PBX sends a disconnect message. BYE. I have a wireshark capture of this happening. It is version 3.4.0.3201 Tom Quote Link to comment Share on other sites More sharing options...
