Hi all,

I am having a E1 PRI connection to the Telco in Vietnam. Problem is the line is working one day, then the other day it is not working, this is repeating.

When it is not working, the E1 is up, ISDN layer 2 is up.

Do you have an advice how to fix this problem?

Thanks & regards,

Le Van Chi

Paste relevant E1 PRI configuration. Post show controllers e1 when circuit is down.

Best regards.

Can you provide me this information:

What version of call manager are you using, call manager express or the cucm?

what kind of voice gateway are you using, mgcp or h323?

can you provide us a show run of those interfaces?
