An end user on a Succession 1000M Rls.3.0 system receives a call from a DID trunk on which the ANI was displayed. The call progressed normally. When the user tries to call back using the same digits displayed by the received call, the call fails every time. What is the most likely cause for the failure?

Answer(s)

1. An authorization code was not entered prior to dialing.
2. The DN set as CLID is the actual DN of the set and not necessarily the DID number to dial to reach the set.
3. The NCOS for the user prevents the call from completing.
4. There is a route control in effect that is preventing the call from completing.

An authorization code was not entered prior to dialing.
