And then, there is ${DIALSTATUS} (without the "j" switch)...
for me, calling the "internal" SIP devices looks like
(lots of lines to read database, set variables....)
exten => _2XX,116,Dial(${SIPDEVICE},${WAITTIME},gro)
exten => _2XX,117,GotoIf($[X${DIALSTATUS} = XANSWER]?120)
(...)

So if the call was answered, no voicebox will take over... and other
niceties like server-side last-caller-listings etc. In voip-info.org
wiki, there should be plenty information how to use the DIALSTATUS.
I decided to not fully follow the example,but itwas helpful to read
http://www.voip-info.org/wiki/index.php?page=Asterisk+variable
+DIALSTATUS
