Standard Call Transfers
To initiate a call transfer in the OnSIP app, select the transfer icon (two opposite-facing arrows) on the dark grey bar on your active call.
A box titled ‘Transfer’ will appear below the active call. Here, you can enter the extension, phone number, or SIP address of the contact to whom you wish to transfer the call. Next, select whether to make an attended or blind transfer to that contact.
A blind transfer, also known as a ‘cold’ transfer, is where the call is immediately redirected to the intended recipient. Your call session will end, and the caller will be connected to the contact you entered.
An attended transfer, also known as a ‘warm’ transfer, is where the first caller is placed on hold and a second call is initiated with the contact you entered. Once the contact answers the call, you can then make an introduction or relay some information before completing the transfer and leaving the call.
In the attended transfer scenario, as soon as you click ‘Attended’ the first caller will be placed on hold, and a second call will be initiated to the contact you entered. Once the contact answers the call, a box will appear under the call asking if you wish to complete the transfer.
In this state, you can speak to either person by switching between the two calls on the left sidebar.
When you are ready to complete the transfer, click “Yes” on either call page.
If you decide to cancel the transfer, click “Cancel”. This will end the second call and bring you back to the first caller. (If the first caller was previously on hold, they will now be active, given that no other calls are active at the time you click “Cancel”.)
Note that an attended transfer is not the same as a three-way call, where all parties are on the same call and can talk to one another. In an attended transfer, the person making the transfer simply has the ability to talk to the intended recipient before the call is transferred. This not only gives the intended recipient a heads up, but can also save time by eliminating the need for callers to repeat the same information to two people.
Drag and Drop Transfers
You can also make a blind transfer in the OnSIP app using the ‘drag-and-drop’ method.
To start the blind transfer, either select the transfer icon in the dark gray bar under the active call, or select the active call on the left sidebar menu.
Once you click and hold the transfer icon or call bar, you will see a translucent image below your cursor that says "drag call to transfer."
You can now drag this image to any contact on your left sidebar menu.
Once you release your cursor, a popup will appear asking if you want to make a blind transfer between the caller and the contact you selected. Click “Yes” to complete the transfer, or “Cancel” to stop the transfer.
