<p class="MsoNormal"><span style="color:#1F497D">The call should stay up if signaling is lost as long as RTP remains active. There’s a “timer receive-rtp” and “timer receive-rtcp” that controls those type of call clearings. In a case like this though, it’s
most likely something about the SCCP communication with CUCM that is resulting in the connections on the gateway not being torn down 100%.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">Thanks Brian. I'll keep an eye on it. I enabled debugs for sccp events and errors so if it happens again hopefully I'll get some information from the router. I have no idea how long these calls have been there.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Do you know what normal behavior is if communication breaks between a bridge and its CUCM while calls are active? Does the call stay up like a phone to phone call or is it immediately dropped?<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">The way I’ve usually resolved these issues is running the show sccp conn hourly until I can identify a recent inactive resource and then pull the realted CUCM traces and search for those conn_id’s until you can
find the call that triggered the condition. Last time I saw this issue, I was able to narrow it down to CSCtx65886 but you should have the fix for that in 9.1.2 so you’re probably looking at a different issue.<o:p></o:p></span></p>
