Any insight on what you've checked so far?</div><div><br></div><div>Is it only reported on 9971's? Is there any other consistency in the reports thus far? </div><div><br></div><div>One of my favorite approaches to get a bit of insight on this type of issue is CMR data. Look at CMR's for "simple" calls - direct call, connection, duration hangup; no mute/transfer/hold/park/etc. If you're using fixed packet rate audio codec (not ilbc) then the packets sent/received should be linearly proportional to call duration barring a few special situations.</div><div><br></div><div>Assuming 20packets per second are the number of packets received appropriate for the duration of the call? </div><div><br></div><div>If the packet counts are correct then it's an audio cut through issue on the gateway or audio rendering issue inside the phone.</div><div>gateway concerns: call going into connected state, any progress indicators exchanged (affect audio cut through timing)</div><div><br></div><div>If the packet counts are off then there is a network issue.</div><div><br></div><div>/wes</div><div><br><div><div>On Nov 2, 2011, at 11:46 AM, Wellnitz, Erick A. wrote:</div><br class="Apple-interchange-newline"><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div lang="EN-US" link="blue" vlink="purple"><div class="WordSection1" style="page: WordSection1; "><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">All, especially you really smart guys at Cisco…<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">We’re at a loss for where to continue looking for a potential cause on a very intermittent issue.<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">Mixed 9971 and 7975 environment with shared lines.
