I seem to have some trouble getting the VFX Call Forwarding Not Reachable option to work properly. I am currently overseas, and I have turned off my ATA at home, and tried enabling the VFX Call Forwarding Not Reachable option to forward all incoming calls to my NZ 027 mobile while I am overseas. I am very certain my cell phone is allowed to roam overseas - I can ring my cell phone directly.
However, when I tried ringing my VFX number, it does not forward the calls to my cell phone - my phone doesn't ring and I get a "calling failed" tone.
I have checked and it seemed that I have enabled the Call Forwarding Not Rachable option correctly - basically the option was turned on, and the phone number that is indicated is 027xxxxxxx (my 027 number).
Have I done this correctly? Am I missing something here?
