andrewgroup Posted August 18, 2011 Report Share Posted August 18, 2011 We have a client running PBXnSIP 4.2.1.4002 (Win32) And the problem is a busy extension, 163 (accounts receivables from customers) receives a lot of calls. Circumstantially, and randomly the 3rd voice mail left on a given day has an unusual set of fast tones, beeps. When hearing the message, you hear the person grumbling, then some tones and a hangup. My thoughts are, perhaps a cell carrier or central office switch isn’t “tearing down” the call normally, CPC stuff, and Windstream the SIP carrier, creates these unusual tones. With this happening on just one extension, the one that normally gets upset callers, it might be related to the carrier. We have a tech call to the carrier, and the next step is we will passively record the entire SIP trunk calls, and get a complete Wireshark trace too. I think we need to Isolate the following PHONE - SWAP Phone with Other Extension PHONE - LAN - PBX CONNECTION (Move Phone to other port/switch) PHONE - FIRMWARE UPGRADES Any comments appreciated - Andy Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted August 19, 2011 Report Share Posted August 19, 2011 Sounds like a problem with the packet ordering on the incoming side. When the PBX encodes that with the GSM codec, it usually generates such strange sounds. Solutions: a) Upgrade to the latest 4 release (which as a fix for this) or switch to uncompressed voice recordings which makes the effect less obvious.

andrewgroup Posted August 20, 2011 Author Report Share Posted August 20, 2011 The system is present set no to compress recordings. We were given a short term license just outside the 1 year support plan for this client to address another issue. The expiration to upgrade to the latest appears to have passed. the client has expressed hesitation to invest in an upgrade to SnomOne Blue, with this outstanding issue. What should we do?

jag Posted August 21, 2011 Report Share Posted August 21, 2011 If you are out of upgrade protection you need to buy a blue license. I dont know where you are from, please contact your nearest snom distributor who can sell you a blue software license. Quote Link to comment Share on other sites More sharing options...
