[Asterisk-Users] custom ring tone

[Alex Vishnev]

Actually that is not true. You can have a short time where audio path is
open prior to answering of the call. This depends on the provider, switch
and software. I think the largest window I have seen is 90 seconds.

So in short you can have a toll free info line without actually paying
for the toll free.  While its not interactive, by not sending answering
supervision the caller is not charged.  Interesting concept they have
there, sure beats the 10k resistor trick from the analog switch days
(although then you could talk to the other person).
