[asterisk-users] Caller ID on Transfers

[C F]

what version of asterisk you using? I use the ${BLINDTRANSFER} a lot
in my dialplans (and I know they work otherwise the users would have
complained) and it works for me using the polycom blind xfer button
(the one that shows up only after hitting the transfer button) runing
polycom sip version 1.5.x

However, when I do a Polycom blind transfer (hit transfer soft key, enter dest num, hit send), the BLINDTRANSFER field is not set. Part of the problem may be that 3254103 STILL HAS CONTROL of the call. I have not pressed transfer a second time yet to release the call, and Asterisk still think that it is attended at this point.
