Try using SetGroup and CheckGroup.  

I use it something like this:

exten => _2[34567]XX,1,SetGroup(${EXTEN})
exten => _2[34567]XX,2,SetGroup(${CALLERIDNUM})
exten => _2[34567]XX,3,CheckGroup(${EXTEN})
exten => _2[34567]XX,4,Dial(SIP/${EXTEN})
exten => _2[34567]XX,103,Busy

Remember to set the group for both caller and callee or you will
not limit them correctly.

Check it out on the wiki:

Good luck,
