Callback Advanced Call Routing

The information contained herein is based on the Callback page but this section handles calls in a more advanced manner. The main difference is the way DISA is used for the dial tone function and how the Dial function is used when making calls.

Dial Command

When the dial command is used the main difference here is that we are using options Tgd in the dial command.

;Call David Klaverstyn
exten => 3,1,Dial(SIP/GoTalk/0416xxxxxx,70,Tgd)
exten => 3,n,Set(TRY=0)
exten => 3,n,Goto(s,start)

DISA

With regards to DISA, it is used in a different context to control the call flow better.
