[cisco-voip] Difference between transfer and conference

[Scott Voll]

No. the calls go out our ASA via the anyconnect client (2.5.1025) out to the
IPC user.

Transcoders are not being used. (checked with one of our tickets)

simply press the transfer say I have X on the line, transfer.

work around ends up being conference, I have x on the line, conferenec, then
hang up.

Technically on a transfer the call coming in is between the VGW and the
(g711)operator,  then a second call is placed from the operator to the(g729)
IPC user.  then a join is used to connect the two if I understand correctly,
thus the VGW and the IPC user should negotiate the Call as G729.

maybe I'm not understanding correctly?
