[Asterisk-Users] Which application to open Zap channel?

[Carey O'Shea]

I'm sure this a very common and easy thing to do with Asterisk, but for
the life of me I can't find the application that will allow me to open a
Zap channel.

Real world example: To be able to connect to an open Zap channel, so it
would allow me to say, join in on a call that was originally answered by
a PSTN phone (ie. just like you would by simply picking up another PSTN
phone..!).

There is ZapBarge, but allows no speaking, which is useless for this
situation. Maybe I just have to use Dial in some way?

Thanks.
