Does anyone know of a reason why a user can call a home/business phone from the US to Germany but not a cell phone in Germany (Just get a busy tone).
Digit Collection Timeout has been extended with no luck.
Dial Pattern is set to 9011T with no luck.
Have even removed all dial patterns and added a user defined 9[0-9]T with no luck...
Try setting sending-complete ?
Your call may be just correct and turn out to be a telco routing issue. Rare, but may happen.
So let's see the trace first.
