Exclamation Denial Event 1220
Hi
I set up IP Trunks between IP Office and Prologix CM. It work fine until the last week, right now if I call from the Prologix to the IPO the call never establish.

When I trace the call in the PBX a get the next error:
Denial Event 1220

I read the alarm manual and it say is a problem with ISDN and Q.931 protocol. If I donīt change anything in the PBX, where is the problem?
Thank you
