Default [Q] Call Management Application

Hi,

I am after some suggestions how I can work with this scenario posed to me today -

I want to be able to divert phone calls from Phone 1 (Android) to Phone 2 (Nokia) but only for a set number of seconds.

I do not want the call to end up on Phone 2's voicemail but to return back to Phone 1's voicemail if possible.

Has anyone experienced this requirement before , can it be done - I have started looking at Android Call Management apps but there are a lot of them!

Thanks
