[Freeswitch-users] Can I stream a file to a parked call.

Fri Aug 28 14:12:14 PDT 2009

Taking over the session while it's parked like that from your code and
asking it to play a file is making it do 2 things at once.
The session's thread is already busy in the park loop so you would have to
change it's state to something passive like soft_execute so
it's thread was not doing anything or send it a message so the park loop
would pick it up by using the uuid_broadcast app::arg

there are variables you can set that begin group_confirm_* that you can set
to do this all without even using a script.
