We are using Cisco 2800 series router as PSTN Gateway on which E1-PRI from different ervice providers is terminating.
Problem which we are facing is DID is not working for one service provider while working for others.
Service Provider says that CLI is incomplete.
Service Provider wants that some extra digits should be added like complete number prefixed by Area Code for him to make DID work.As of now, when call is made, Pilot number is displayed at receiving end.
We are using dial peer pots & voip.Is it possible to add some extra digits when any call is made from IP phone to PSTN world?
