<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">with 8 sccp 7937s and all of them are experiencing the same
problem. Intermittently</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">throughout the call they continue to lose voice for 5-10 seconds
and then it</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">clears back up for a few minutes and it occurs again. I can see on
the web</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">statistics for the phone that it appears to be losing packets
(Rcvr Lost</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">Packets 2483). This only appears to be occurring</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">inbound to the device since the caller does not hear and audio
issues. These devices</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">are deployed throughout the company and all are experiencing the
same issues at</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">times. There are a couple bugs for g729 and g722 but we’re running
g711 (g722</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">has been disabled clusterwide). They were experiencing the issue
yesterday and</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">I had the 7937 conference in a 7965 and the 7965 did not
experience any voice</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">issues so it’s not the call itself or callers phone. No other
phones are</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">experiencing the issues and I’ve upgrading the load from 1.3.3 to
1.3.4 and the</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">problem still exists. Calls are hitting the PSTN via an MGCP
controlled PRI</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">however I’m not sure if that’s in play or not we have not been
able to</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">replicate the problem on internal calls but that’s not to say it’s
not occurring</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">because its intermittent.</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">No Duplex Mismatches</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">Cabling has been checked and</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">device moved to new location with known good wiring</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">CUCM 7.1.2.21900-5</span></span></p>
<p class="MsoNormal"><span><span style="font-size: 8pt; color: black;">Any ideas?</span></span></p>
