I am having problems with a SIP trunk which is terminated by my ISP. I can make outbound call fine but inbound calls are just engaged. I know the IP is being send from the ISP because I can see packets through the firewall and if i unplug the call manager I get number not in use when I call it.
I have no idea where to look on a Call Manager 5 server to do any debugging. Any help would be greatfully recieved.
