Hello everyone.
Please, could anyone explaing, if a 183 "Session in progress" message is
the only thing needed for generating ringback? Another question is where
do those ringbacks come from (who generates them?).
I'm having a wierd problem of not having ringback when dialing some
particular numbers (asterisk 1.2.18).
Thanks in advance
