In the 1.4.x firmware release, there was a config file setting that would
cause the screen focus to change to a new call that came in whilst a call
was in progress. When set, presentation of a new call would cause that call
to be selected, and the softkeys would display Answer, Reject, Forward.

Has anyone else noticed this or had experience with it? We like the
features of the new firmware release (like being able to split a conference
call then drop one party) but the change in behaviour of call waiting is
giving a few users grief.
Look at the 'callwaitingprompt'
