[Freeswitch-users] A DTMF issue

[Steven Ayre]

- checks whether the session is still active (true anytime between call
starts and hangup)
- also session:ready will return false if the call is being
transferred. *Bottom line is you should always be checking
session:ready on any loops and
periodicly throughout your script and exit asap if it returns false.*
