Hi, we have CUCM 7 and Unity 4.2 at central site and 3 remote sites (A, B &C) with voice GW. Now we are having a issue at remote site A, when outside customer called site A's external number and left the voice message, the user couldn't hear that message clearly since the voice was broken, but if I called internal number and left message, that's working fine. Site B & C don't have this issue. I did some tests, all is fine except I called site A external number to left voice message. I compared the router config between site A, B & C, it seems be OK. I checked with ISP and they said QoS has been enabled on the MPLS circuit. Anyone has any ideas how to troubleshoot this issue?

When you were placing the internal test calls, where was your phone located? The RTP streams are usually only set up between the two endpoints (assuming no transcoder or MTP is used).
Have you have already checked calls between IP phones at your central site (where Unity is located) and IP Phones at site A? Are these working fine? If not, then it's likely you do have a QoS issue over the WAN to Site A.
Have you confirmed whether or not calls from the PSTN gateway at site A experience any voice QoS issues when transferred to an IP Phone at the central site?
Is the same codec is being used for the MGCP gateway as for IP Phones at that site (check the Region settings for the Device Pool it's in)?
If these things have all been checked, then you may want to consider collecting a simultaneous sniffer trace from each end of a single call, and comparing what's seen at the two endpoints.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
