You’ve probably tried these basic trouble shooting tasks… In an attempt to isolate where the issue is happening:
I’d target the following: 1) Are calls inside the network fine 2) Bypass the InGate (maybe try voip.ms for some outbound…cheap and quick) Narrow down where issues are happening – if they recently changed internet speed… It sounds like something is eating up bandwidth on the download side of things. Maybe throw some QOS settings on the internet router. It could be an issue on a router out of your control between them and the ITSP.

"2011-07-28T08:13:47.439922Z":10822972:SIP:ERR:sipx.ebbrown.local:SipUserAgent-2:B6CFDB90:SipXProxy:"SipUserAgent::handleMessage SIP message timeout expired with no matching transaction" We have a client who is using a SipXecs system with sipxconfig version 4.0.1-015823 For the past couple of days they’ve had issues with call quality. On their end of the of the call the words were broken up, but on the other end of the call the quality was fine. At times the quality was so bad they couldn’t make anything out. They recently upgraded their internet speed, but the ISP has tested and notices no issues. We have rebooted the SipXecs, the Sip GateWay (An InGate), the firwalls, network switches, etc. After rebooting all these devices, the customer reported that the call quality was good. However the date/time were wrong on the phones and they couldn’t transfer between extensions. We sent the profiles to all the phones and forced them to reboot. This resolved the transfer issues and date/time issues for the users we were able to speak with at the time. However a few hours later, we received reports that they couldn’t transfer calls in one instance, then on another call they could. They also reported that the call quality was choppy on their end again. Does anyone have any suggestions on this issue? We are looking through the logs now. What logs do we need to look at specifically for this issue? Before we start looking at replacing the POE switch or other equipment, we just wanted to check and see if anyone has any suggestions. ________________________________ ________________________________ This message and any files transmitted with it are intended only for the individual(s) or entity named.
