[Freeswitch-users] A DTMF issue

[Steven Ayre]

You should be checking session.ready() in that loop, as it is I think you'll
find the scripts are never ending when the channel is hung up.

streamFile/flushDigits probably return instantly, but then get called again
on the next loop iteration. The problem would get slightly worse after each
test call since there would be an extra copy of the script running.

Try replacing:
    while(true) {
with:
    while(session.ready()) {
