[Freeswitch-users] fifo questions

Hi, I'm using mod_fifo with onhook agents, and when a caller in it will ring all agents. The problem is that if an agent is placing an outbound call and the fifo still ring it regardless it's "busy". I manually set on the phone to accept only one channel solved the problem. But mod_fifo still try to ring it, is it possible to not ring the "busy" agent? I found fifo_track_calls, might work with this? also, what's the purpose of fifo_add_outbound? should it have a difference with fifo_member add ? Thanks. -- Seven Du Sent with Sparrow (http://www.sparrowmailapp.com/?sig)
