[Freeswitch-users] long DTMF

[Nyamul Hassan]

I did read your emails, and I thought the Lua script idea was nice.  The ESL
was more complicated, but also good.  But, you didn't accept either.  So, I
was wondering, is this "bind_long_DTMF" something that allows you to capture
DTMF during the full length of the call, i.e. even after bridge?  Is that
what you wished to accomplish?

Regards
HASSAN
