Interface shutdowns in loop because of DSP

Hi,

I use Cisco CUCM 12.5 with an MGCP gateway.

Actualy, my calls randomly fails. Sometimes they work, sometimes not.

I realized after looking in the debug logs, that the interface shuts down, and restarts.

 

I don't know what that means.

Any idea ?

 

Thank you in advance.

@admincoco I believe I am experiencing the exact same issue with our Cisco 2951.  Did you happen to replace the PVDM module in the router for the solution? 

Hi Kyle,

The suspicion was on the PVDM card but we decided to change also the the T2/E1 card in same time. Not that expensive as second hand and I don't like to waste my time going to DC in case the PVDM was not enough.
