[A*UG] Polycom and Caller ID

[Jim Freeze]

Hey Gil

Thanks for the info on Progress (and more). I'll look into that.

For my particular system, I am using Adhearsion and sending calls to an AGI.

Assume I have the following dialplan:

[inbound]
exten => 6825,1,AGI(agi://127.0.0.1)

Then the AGI dials the local sip phones. In this case, is there a need
to ever execute Answer(), or is that automatic when Dial is called?

And, I'm not sure, but should I change the dialplan to be:

[inbound]
exten => 6825,1,Progress
exten => 6825,n,AGI(agi://127.0.0.1)

Jim
