I have a problem in a FXO to FXO connections.
I am using Cisco routers with VIC-4FXO and CUCM 6 with MGCP protocol.
This is a schematic view of my scenario:
[telephone A]________[PBX A]________[router A]________[router B]________[PBX B]________[telephone B]
All functions like disconnect supervision work fine except in case below:
When station A calls station B, telephone B starts ringing. Before B answer the call, station A disconnect the call BUT telephone B remains RINGING continuously forever.
I also tried "timeouts wait-release" command, but it doesn't helped.
Any ideas???
Beside the main problem I tried to limit the maximum number of rings by "timeouts ringing" command, but doesn't worked. How can I limit it in router or CUCM?

Are you running a back to back FXO connection? For example:
pbx---router-fxo---fxo-router--pbx
If so, this is your problem. If you are running a back to back analog line, one end must be FXO, and the other must be FXS.
