[cisco-voip] D channel errors - carrier or us?

[Lelio Fulgenzi]

Over the last few months, I've had sporadic D channel errors. Am I correct in suspecting carrier issues? Typically, if it's a problem on our end, we'd see other errors like unregistered gateways, etc.

I don't have any more log details from the 6608 ports, but the one port on our 3945 had this information in the logs at the time:

Jul 13 2012 04:35:17.644: %MARS_NETCLK-3-CLK_TRANS: Network clock source transitioned from priority 10 to priority 1 

Should I be looking in CallManager logs for more information at this time?
