I have a Cisco SPA502g attached to an Asterisk based system. When the user's phone is attached to a call queue and dials digits on the phone without picking up the receiver, then hits tthe dial softbutton, if a call came into the queue at the same time the user hits dial then the line is answered by dial and digits are played into the callers ear.
I'd like to make it so hitting the dial soft button doesn't answer an incoming call, but starts another, ignoring the incoming call. How can I do this?
