Please provide me a list of carriers that support 2BCT but don't bill for any calls that are released back to their switch. I want to abuse the hell out of it. On 9/19/2015 8:35 AM, Jay Ashworth wrote:

From: "Jared Smith" <jaredsmith at jaredsmith.net> I helped consult on a similar system eight or nine years ago -- at the time, my client used Asterisk with PRI channels instead of SIP channels, because of the ability to do a two-B-channel transfer and cut himself out of the middle of the call after the connecting the caller to the called party. Asterisk can initiate the two-B-channel transfer, but as far as I know doesn't yet do anything with the message coming back down the PRI letting it know when the call has terminated. (Well, that's not entirely true -- Asterisk logs an error message, so I assume it wouldn't be too hard to actually connect that up to some sort of better logging to be able to determine the call duration.) 2BCT is great stuff, if your carrier will give it to you: you don't pay for the minutes except when they're on your trunks -- and if they're local trunks, they may still be free cause they're incoming.
