Hi James,

As long as you just use Dial to call your extension, and don't use
Answer the caller shouldn't be charged. That's how it appears to work
here.

Caller not charged:

  exten => s,1,Dial(SIP/sip123|tr|20)
  exten => s,2,Congestion

Caller charged:

  exten => s,1,Answer
  exten => s,2,Dial(SIP/sip123|tr|20)
  exten => s,3,Congestion
