External forward - Temporarily Unavailable (480)

[PENGUIN]

Hi All,

I have one instance with one SIP Trunk added and configured to forward calls to a call queue, I have configured office hours and the behaviour so that if the office is closed all calls are to be forwarded over to an external number, however no matter which number I try I receive the error "Call or Registration to xxx@(Ln.10000@Test Trunk) has failed. sip:93.95.xx.xx:5060;lr replied: Temporarily Unavailable (480)". I have verified I am able to make calls to the main trunk number with no issues and outbound calls to, only call forwarding has an issue.

Hi,

If the call is making it out to the Trunk provider, they might be better able to let you know what's off.

Could it be that the Caller ID of the forwarded number is being sent, and is not approved by your provider?
