Hello,

So, your config looks good.

Pelase, can you explain what you mean when you say:

"-3905 failed without power but the call still ringing on mobile phone."

You can try a "debug isdn q931" on your gateway and see if the disconnect is ok. Use the documentation bellow to understand the debug:

http://www.cisco.com/c/en/us/td/docs/ios/12_2/debug/command/reference/122debug/dbfipx.html#wp1018126

If the disconnection is good, you will need to understand your call flow.

Phone -> CUCM -> Gateway -> PSTN -> Called Party

The final disconnection point is provided by your telco, and it can send the disconnect late.

Please, let me know the result of the debug.

best regards.
