问题
I want to create an iPhone application which will display notification that an incoming call is being forwarded from an outside line, to my iPhone.
Purpose being, I have 3 separate office land lines that forward calls to my cell phone after hours and I would like to know from which they are coming from.
is there any possible way ? Kindly help,thanks in advance.

On an unjailbroken phone, you cannot interfere with incoming calls in any way.
On a jailbroken phone, your ability to do this depends on the phone system that's doing the call forwarding.
