Question : International calling

I just set up a Cisco CME voip system for my company, calls are coming in and going out fine except when an international call is placed more than 14 digits there is a busy signal. Does anyone have an idea what would be causeing this.

Answer : International calling

I see that you are forwarding the 9 on your dial-peer, is this a Centrex line?  Do you know if it is provisioned for International dialing?  If it is an analog line, can you hook an analog set to it and test the same number?
