Firstly thank you for your response. I understand that setup will work and am using it now but from my experience it will still route the call through my box. My understanding is that when a call comes in from 777-777-7777 to 888-888-8888 and asterisk takes it, issues a Dial(SIP/999-999-9999@provider) the call will still be handled by asterisk incurring charges with the provider via the Dial command. Yes? My understading follows that I will have an inbound call with per minute charges from 7777 to 8888. I will also be handling an outbound call with per minute charges from 8888 to 9999 essentially being double billed for redirecting a call. I want to drop totally out of the picture (like say when I set up my cell phone to forward or a “regular” PTSN forward does) have the call running directly from 7777 to 9999 with the 8888 number non existant in the call so that I am not charged for creating and maintaining the bridge.
From what I have read now though here and elsewhere I don’t think it is possible.
