Hi Daniel,

It fails the call, well doesn't respond;

2015-07-14 10:49:38] NOTICE[15318]: app_dial.c:901 do_forward: Not accepting call completion offers from call-forward recipient Local/*33331022-MAGNORTH13@from-outside-00000001;1

[2015-07-14 10:49:38] NOTICE[15318]: app_dial.c:1003 do_forward: Forwarding failed to dial 'Local/*33331022-MAGNORTH13@from-outside'

The callid re-write is a good idea, as I tried it manually and it allowed connection, I will try that.

I will also consider your other option.

Many thanks for the prompt response.
