I have one station that all of a sudden is displaying access denied when trying to make a call to another extension off-node. This extension can dial other extensions on the same node.

I checked the settings under device and feature codes/endpoints and they appear to be the same as the other extension that don't have a problem.

Where else should I be looking?

Access Denied on an intercom call? I've seen that for trunk access trying to get to a group you are not allowed to call. Destination Unreachable for trying to call across nodes, but never access denied on IC call. Other extensions can make a call to the extension you are trying to call?
I think I would try 2 things first a reboot of the phone system then if that doesn't help try import/export

Could that station have been removed from the extension list used for outbound access to the remote node?

If it's using P0051, there should be no problem.

This extension can receive calls with no issues. Just IC calls off-node get the Access Denied. I have no idea what could have changed here.

I checked PP051 and the extension is listed. It was not listed in P0001. I added it then did an import/export. Problem Resolved.

Thanks guys, I had checked the Trunk Groups and I though the Extension Lists. I must have overlooked it.
