Hello,

Have you tried restarting the channels on your end? Try doing a shut/no shut on controller e1 0/0/1, voice-port 0/0/1:15, and serial 0/0/1:15 and see if that resolves your issue. If not, I would contact the service provider and have them check the PRI at both layer 1 and layer 2.

Hope that helped, if so please rate.

Hi,

Configure network-clock-select in your router.

Hope it helps, if does please rate.

Best regards.

Check "show controllers E1". Most likely you have slip errors and need to take care of tat as indicated above.
