Help Pls: Call Forwarding when Busy

My wife is now using my 2G iPhone and one of the call features she uses most is Call Forward if Busy for many years on her other phones.

I've enabled Call Forward if Busy on her iPhone using her carrier codes ie. *67*[dest]#. It works fine when the screen is not locked as she is able to "Decline" an incoming call to initiate the Call Forward if Busy to another number. The problem arises when the screen is locked. When there is an incoming call the only option is "slide to answer" and there's no way of declining a call in screen lock mode.

She doesn't want to directly Call Forward because (i) there are times she will forget to cancel call forwarding (ii) Call Forward if Busy allows her to screen calls.

Does anyone know of a solution apart from putting the Auto-Lock to Never? Is there an App in Installer that allows for better Call Fwd function or puts more call answering options when the screen is locked?

 

THANKS!

That worked!
