[Freeswitch-users] Sound not OK (Choppy Sound) while using ManagedSession (.NET/C#)

[Phillip Jones]

In example two you are parking the call. You are then playing media into a
parked call. I am not sure this is valid. According to the wiki "Please note
that to retrieve a call that has been "parked", you'll have to
bridge<http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_bridge>to
them or transfer the call to a valid location." - so you might need to
transfer that parked call to a DialPlan App before you try and play media -
or just not park it in the first place.

I might be wrong - but that where I would start.
