Hi, can you check "show controllers E1" or T1 if you have that for slips ? Chances are you need network-clock commands

Hi, no slips but many errors. Monitor the router and check if at the time the calls drops, the errors increase.

Turned out to be a DTCI equipment on the network side of pstn. Also, Cisco looked at the GW and couldn't find anything wrong.
Thank you.
