To transfer calls to another extension, you might want to use the call parking feature. This lets you place the call on hold, chat with your colleague, and when they are ready, they can accept the call. You can also transfer the call by using the call transfer button that may appear on your VoIP desk phone. Additionally, the VoIP app includes a Transfer Call feature to direct the call instantly to another extension. Call flip (call pulling) is ideal for transferring calls to another device that you use, not necessarily another person.
