font-family:"Arial","sans-serif";color:black">I have a new customer install
with 8 sccp 7937s and all of them are experiencing the same problem. Intermittently
throughout the call they continue to lose voice for 5-10 seconds and then it
clears back up for a few minutes and it occurs again. I can see on the web
statistics for the phone that it appears to be losing packets (Rcvr Lost
Packets<span style="mso-spacerun:yes"> </span>2483). This only appears to be occurring
inbound to the device since the caller does not hear and audio issues. These devices
are deployed throughout the company and all are experiencing the same issues at
times. There are a couple bugs for g729 and g722 but we’re running g711 (g722
has been disabled clusterwide). They were experiencing the issue yesterday and
I had the 7937 conference in a 7965 and the 7965 did not experience any voice
issues so it’s not the call itself or callers phone. No other phones are
experiencing the issues and I’ve upgrading the load from 1.3.3 to 1.3.4 and the
problem still exists. Calls are hitting the PSTN via an MGCP controlled PRI
however I’m not sure if that’s in play or not we have not been able to
replicate the problem on internal calls but that’s not to say it’s not occurring
because its intermittent.</span></span></p><p class="MsoNormal"><span class="apple-style-span"><span style="font-size:8.0pt;
