[VoIP] How Do You Turn On Audio During Call Progress?

[Brent Jones]

Thanks for that Russ.  I'll try it in the next few days.
The Asterisk box is actually at the museum I volunteer at in the 
Telecommunications section.
So it means it takes a while to try new things out.

I have decided to use an old office PABX that uses twin Reed Relays as the 
switching element
to interface between the Asterisk and the EM Step by Step PABX (uniselector 
driven).

As well as letting people ring in from CNET, visitors at the museum will be 
able to dial in and
listen to the different recordings as well.

So when I finally get the Asterisk box setup it will become an exhibit in 
it's own right.  I plan to put it next
to the working magneto phones for the contrast.
