To transfer your call, click the Transfer tab at the bottom of the call window.
In the Transfer tab, select a person to add from the selected directory and then click the Connect button to call them.
On the Transferring screen, you'll see VPW calling this new person and waiting for them to answer. You can also talk to them one-on-one during this portion of the call. To complete the process, click the Transfer button either before or after the new party answers the call.
