[asterisk-users] Attended Transfer

[Henry.L.Coleman]

Thats quite correct however if you have a multi-line phone like
Grandstream GXP 2000 or Aastra 480iyou can put the call on hold manually.
As for using an ATA, You can program the ATA using the "vertical" service
codes. In this case you can use a code to tell the (SIP) ATA that you want
to do a transfer. You must make certain that the code you choose doesn't
conflit with Asterisk's feature codes.
