I've issue at Cisco ISR 2811 CCME 4.1 with AIM-CUE (ver 3.0.3). I have script where possible to dial-by-extension. When I'm dialing by existing extension - all ok, but when dialed invalid extension number I hear silence. When IP Phone is busy - CUE can't understand that and I hear silence too.
I had test that script for invalid numbers and busy with CUCM 6.1, script worked fine.
Could you tell me plz, whats going on?
