[Freeswitch-users] Why ringback is not generated?

[Ken Rice]

On FS2 did you pre-answer the call? That will put FS into the state to start
generating early media... And you¹ll probably have to sleep or something to
delay the exchange long enough to actually get ringing... Just playing a
file and firing a script to check a pin or something and firing a DB query
happens so fast that 99.99999% of the time its worthless to send ringing
