[Asterisk-Users] Detect Dialtone

[Goran Dj.]

Dialtone detection should be an option in .conf for zap channel, i agree
with that.

Belive or not, but at some places on the world are still in use some old
(non-digital) ATC-es which do now provide dial-tone instantly. For
example, when ATC ARF-102 is very congested with outgoing calls, you
must wait some (unknown) time to get dialtone (10sec, 1min, 5min...)
