Hi, I'm having trouble getting external incoming calls to forward externally. We are London based and have a Spitfire SDSL line which I believe has passed compatibility testing with 3CX. We have DIDs but a couple of extensions are for people who are always out the office and need all their calls routed to their mobiles. I have tried the 302 Diversion option in Forwarding Rules in Out the Office and Away but can't get it to work. When you dial their extension it seems to get as far as Spitfire and you get a recorded message. You also get the same message if you just use the Forward to external number. The external forwarding works from internal number but external numbers seem to call out but seems to be stopped by Spitfire. Is there anything I've missed to set this up?
