How do I transfer a call with My.OnSIP to another user on my PBX?

To transfer a call in the "Open Lines" section to any other user on the PBX, simply click on the active call and drag it onto the "Contacts" list. Drop it on the person you wish to transfer the call to and the call will be sent to that user. Of course, you may use the IM interface to check with the user prior to sending them the call. This is a 'blind' transfer.
