The first place to look is MGCP packets being lost. Search for “Retry” in the ccm traces similar to: CCM|MGCPHandler TransId: 1476004 Timeout. Retry#1
That example is from a case in 2008 so what you see may not look exactly the same. This type of message is an indicator that CCM is resending an MGCP message that wasn’t Ack’d by the gateway. After 3 or so of those CCM will unregister the gateway and any phones talking to it will get Temp Fail. Aside from lost messages it could be a RSIP or something that is gateway initiated causing the reset. -Ryan On Apr 5, 2015, at 10:15 AM, Jason Aarons (AM) <[email protected]<mailto:[email protected]>> wrote: Nothing has changed with MGCP for a long time…Cisco just doesn’t test older IOS.

Cisco TAC looked at RTMT with me today. They want us to set up packet captures and try to duplicate the problem tomorrow. I am just wondering if this is an upgrade issue that anyone else may be experiencing since we had no problems before the upgrade.

Thanks, Ryan -------- Original Message -------- From: Lisa Notarianni <[email protected]<mailto:[email protected]>> Sent: Monday, March 30, 2015 04:48 PM To: [email protected]<mailto:[email protected]> Subject: [cisco-voip] Temp Fail since upgrade A few weeks ago we upgraded Call Manager and Unity Connection from 8.6.2 to 10.5.1. We have experienced 2 intermittent outbound calling issues: 1. “Temp Fail” shows on phone display and only option on phone button is “End Call” 2. Outbound callers dial a number and hear nothing but notice the phone display says “Connected”. Caller cannot hear anything. Person they called cannot hear anything. ***These issues are only intermittent.*** We had no issues before the upgrade. Is anyone experiencing the similar issues? Thank you in advance. itevomcid _______________________________________________ cisco-voip mailing list [email protected]<mailto:[email protected]> https://puck.nether.net/mailman/listinfo/cisco-voip
