A remote extension reaches an external phone by automatically selecting a line from a trunk and dialing the phone number. For example, a remote extension can reach an employee’s cell phone or home phone, or a phone at a branch office.
A caller can connect to a remote extension through the auto attendant, or can be transferred to a remote extension by a call cascade. A user at a local extension can manually transfer a caller to a remote extension, or can dial a remote extension directly. If the remote extension is busy or unanswered, the system can route the call using the remote extension’s call cascade.
