I am not sure if I completely understand what you are trying to do, but it 
sounds like you want to query the DEVICE_STATE function.

For instance, my customer service department has this thing against ever 
having their phone ring a call while they are already on a call, so for 
these special little snowflakes, I have  the following line:

same => n(voice),GotoIf($["${DEVICE_STATE(sip/${EXTEN})}" != 
"NOT_INUSE"]?voicebusy)

Basically, this little line looks at the extension and if it shows 
anything other than free (NOT_INUSE), it jumps to the voicebusy line in 
the dialplan. The voicebusy line just hits voicemail directly.

You can use this same idea to branch your logic and handle a variety of 
situations. In my case, I only want to actually perform the dial if the 
phone is currently not in use, so my logic was fairly simple.
