[Freeswitch-users] Removing FIFO's on-hook agent in case of unsuccessful bridge

Hi Guys, There are some situations which logged in on-hook agents don't respond to assigned calls by FIFO (USER_BUSY, NO_ANSWER, ...). I want to remove those agents automatically. I've considered it already by using loop backing dial string to another dial-plan and track what will happen to bridge application. In this technique I have troubles with additional xml-cdr posts, bridge_hangup_cause and transfer_after_bridge variables. I'll appreciate if know there are some other techniques except this one.
