Out of Office call forward on a ring group - v20

[netech]

After V20 simply having a call forward to an outside number no longer works on this pbx. The call is forwarded to the number on the correct sip trunk and I can see from wireshark that the call is answered.
Once answered the message "We're sorry your call could not be completed at this time. Please hang up and try your call later." in an American accent. I cannot find any wav file in 3cx that matches this text. The SIP provider says as the call was answered there is no problem on their end even though the RTP of the text is coming from their end.
Any ideas?

If you are able to see, in Wireshark, or one of the 3CX Logs, that the call is indeed being sent to your provider, and being answered, then perhaps the recording is what is to be expected.

Is this happening on all calls forwarded to various outside numbers? Have you called these numbers from another line to confirm that they are working? Could there be an issue with the caller ID you are sending that is causing this response?

Your provider should be able to offer more information, I'd go back to them.

Is there any "code" after the "Please hang up and try your call later". Sometimes the switch providing the recording will offer a code so the final destination can be traced.

The problem with TPG is that the diversion field must contain the same details as the invite header. That is [email protected]. But in the 3CX the diversion field it populates with [email protected]. Hence the rejection with a carrier message of "We're sorry your call could not be completed at this time. Please hang up and try your call later."
