I have an issue with conditional forwarding from another mobile network (o2) to my new iPhone 6 Plus on the Three network
Unconditional forwarding i.e. all voice calls the divert works fine and the call to the o2 number arrives immediately on my iPhone on the Three network.
However if I set a conditional forwarding i.e. forward if not answered after x seconds, if out of reach or if not available the call will does not arrive and you get call disconnected tone as if the call has been rejected.
I initially thought this was problem with o2 but have disproved this as conditional forwarding to other numbers mobile and fixed line works as expected. I then suspected the Three network but have disproved this as I have successfully set conditional forwarding from the o2 number to another iPhone 5 on the Three network.
All I can think is the iPhone is somehow rejecting the call on conditional forwarding? It works fine on unconditional forwarding though. The o2 number is not blocked on the iPhone which makes sense as it would affect unconditional as well as conditional.
Totally miffed anyone else experienced an issue like this and any pointers as to what could be causing the issue?
