Hi guys,

I found a problem in my router 2911, i think that is a config mistake, let
me try to explain.

In the beggining i thought that it was IOS problem so a made a upgrade
from c2900-universalk9-mz.SPA.152-4.M6a.bin to
version c2900-universalk9-mz.SPA.154-3.M3.bin

I have this same configuration at the some router on another interface an
this is not happening.

Analog Phone -> FXS Post -> Branch_Router -> CUCM -> IP Phone  [Call is
completed, Voice is Working, No Problem]
IP Phone -> CUCM -> Branch_Router -> FXS port -> Analog Phone [Call is
completed, Voice is Working, Problem]

When the remote users answer the call, in the beggining of the call i can
hear a sound like the phone was trying to dial a number, for me seems that
the router is not understanding that is an incoming call and when the user
hang-up the phone the router is trying to dial the number configured at
connection plar at this voice port.

Anyone already have the same problem?

Thanks.
