I have a UC500 running IOS 12.4.(22)T, CME 7.0.l, and CUE 3.2.1 and I need to make outgoing international calls.
I confirmed my ISP is not blocking the calls but when users dial 9+011+44+number they get a fast busy.
What digits are you sending and what digits is telco expecting?
What numbering plan?
Do they expect a certain ANI for the calls?
Look at a debug voip ccapi inout to see the exact cause.
if this helps, please rate
I dont know the system that well. The output for 1 call is 18,000 lines char to much to post
