So we've setup a new SIP trunk in our MiVB. The carrier says it's registered.
We can't make outbound calls on it. The users get Access Denied.
The SIP Trunk has the same COR as the other SIP trunk that works. 5 in this case.
All the phones are assigned COR 3
The ARS routes uses COR groups 1-9, depending on the ARS Digits Dialed.
COR 3 doesn't appear is any of the COR groups so I expected to be able to dial out.
COR 5 does appear in some of them.
Now the working SIP trunk uses COR 5 as well, hence why I used it again.
Is there somewhere else I need to allow outbound calls as when I change the ARS to use the new SIP trunk, with all the same COR values, it fails with access denied.
