Update the SLAStation application to account for the case where the SLA thread
has a call out to the station,  but the user has pressed a line button to answer
the call instead of picking up the handset.  If they do, the phone sends out a
new INVITE.  So, the SLAStation app must check to see if it is picking up a
ringing trunk, and ensure that the other stations stop ringing.

(reported internally, patched by me, tested by mogorman)
