If you've received a call but it'd be better handled by someone else on your team, you can pass the caller over using Cradle.
To transfer, click on Transfer. You will be presented with a list of your team. Click on the person you want to transfer the call to.
Cradle will put the caller on hold while you call your teammate, and you can introduce the person. Once they answer, click on the blue Transfer Now button to transfer the call. If the person can't help or doesn't pick up, click on the Back to Callbutton to be reconnected to the caller.
With Cradle, your call transfers are a warm transfer so you will always have to speak to the person you are transferring the call to.
