Access Denied for outbound calls over SIP

(1/1)

PokerMunkee:
My Mitel tech made a change yesterday which broke all outbound calling over our ESI SIP trunk.  He was trying to get SIP calls going over our MBG virtual server, I believe.  Every phone gets "Access Denied."  He reverted the changes but nothing has worked.

He created a ticket with ESI but we've been down almost 48hrs.  Inbound works fine.  He's doing packet captures with no luck.

Any ideas what could be going on or what I should look into on our 3300?

ralph:
I would do a packet capture on the SIP trunk and see if the call is actually hitting the trunk at all.
It is is, reviewing the packets may give you a clue.
For example, it may be rejected because the Caller ID is not correct.

If you don't see the call at all in the SIP traces, then then it's going to be in one of the following:
COS, COR or Tenant.

Typically Access Denied is a COR issue in my experience. The new trunks may not have the right COR to access them.

acejavelin:
"Access Denied" is almost always a permissions problem, usually a Class of Restriction (COR) issue...

might be a calling line id problem - have seen this before when an invalid number for the trunk was being sent
