Hi Matt,

Sadly I understand all to well how transfers work. I've had to go over and over 
this for the last 12 months trying to find different ways of handling it. I'm 
talking about blind and attended call transfers here not IAX or any other kind. 
We are not taking Asterisk out of the media path and even if we were you 
wouldn't want to be losing CDR's from a provider's point of view, whoever set 
the call up is still paying for it regardless of where the media has been 
re-invited to.

Out of the 8 Asterisk based providers I have tested 3 have this issue and the 
other 5 don't support transfers.

It's dead simple for anyone to test. Find an Asterisk provider that supports 
transfers, connect with the xten, do a blind or attended transfer and check the 
CDR's. Call a free or cheap destination as the first leg of your transfer and 
the expensive destination second. You'll be pleasantly suprised at the bill!

Regards,

Greyman.
