All

I am looking for a little help, We have and FXO port in a Cisco 1861 router. When someone phones the FXO port, it rings on the IP phone, but as soon as the phone is answered the call is disconnected / dropped with click pretty much instantly.

This is the same for inbound and outbound, I cannot find anything to explain why.

I have pasted some config below, but can provide more if needed.

Any help would be most appreciated.
