The following document describes how to transfer using an analog phone:
First, the Channel Group must have "Transfer" and "Three way calling" allowed in Channel Admin. This will allow you to use a hook flash to perform a transfer.
Go to System Setup → Channel Admin to modify the FXS channel group. Then look for "Transfer" along with "Three way calling" and enable these.
...
While on a call, hook flash to switch to a new line. This will also put the current call on hold.
Dial the extension you want to transfer to and wait for the new call to connect. At this point the first call is still on hold.
Hook flash again. This will initiate a three-way call.
Hang up your phone. The first call and second call will still be connected, and the transfer will be complete.

Note: This is equivalent to an assisted transfer on a SIP phone. |
