[Freeswitch-users] Another fifo request

Yah, your right. it works...but it must be set on the fifo out channel
(consumer's channel), it will not execute if it's set on the fifo in channel
(caller's channel). Also api_after_bridge does not execute...but as long as
bridge_pre_execute_a/bleg works, I'm super happy. Thanks.
