Hi Guys,
I will appreciate your input on this problem. I have setup a FXO port as a gateway to the PSTN network for a lab IPT POD. Outbound calls work just as expected but inbound just doesn't work at all.
Rings are heard at the calling end but not called, but after 3rings the calling end goes dead whiles a check on the gateway still indicates an off hook.
It's a BT (British Telecom) analog line by the way.
Any ideas? Port configs below.

Common Problem....
For example, if you have extension 4444 that you want all your incoming calls to goto you need to do something on the router.
Go into configure mode and into the voice-port interface that your incomming calls are coming into. ie: Voice-port 1/0/0
Add this line:
connection plar 4444
Ctrl-Z and write the config. Try dialing into the voiceport now and extension 4444 should ring on your voip phone. In my systems of FXO dialin, I take the extension specified in connection plar xxxx and point it to a basic IVR 100% of the time that lets you move the incoming caller about the system.
Hope that helps!

Cheers!! PLAR works fine and this question is juet food for thought.
I trust translation rules can fix this problem too. I not sure if CLI / callerid comes though on the line but my intention will be somthing like this ....
translation-rule 1
Rule 1 ^. 01908601000
On the voice port.
What are your thoughts?

Could you show the config, especially the dial-peers?
