To explain what what is in these logs:
2712xxxxxxx - main SIP Trunk on 3CX
41.xx.xx.xx - IP of SIP Trunk provider
Extn:399 - the dummy extension that needs to forward to a external number
2781xxxxxxx - external number dialed from
079xxxxxxx - Mobile number to forward to
When calling ext 399 form a local extension it forwards with no problem, its only when a external number calls in and then needs to forward. The option in Settings/General that allows forwardings to external numbers from queue/ring groups is checked.
3CX Version 12 SP6.1
Any help would be greatly appreciated.
