Hi All,
I am running CUCM v 12.5.1. I have Extension mobility setup for the users.
When I try to make a regular outbound call to any working PSTN number, it works fine.
However, when I call to a mobile number which is switched off or out of coverage area, I keep hearing Ringbacks. Whereas, I should be hearing a provider message like "The number you are calling is switched off or out of coverage area".
I took debugs and all I can see is that the voice gateway receives Progress 3 times and then a Connect. The line stays connected for around 10 - 15 secs and then busy tone.
I am attaching the debugs herein. Has anyone come across a similar issue?
