The device also comes with an Auto Attendant for helping callers to direct their calls landed on the
device. When an inbound call is received on the device, it can be routed to the AA, which then offers
a menu of options to the caller to direct it further. It could be directed to ring any one or all of the
available Phone ports, or bridged with another call on a trunk (which the AA “dials” or sets up on
behalf of the caller).
The Phone ports and the AA are the two entities in the device where calls can terminate (that is,
start or end there), as opposed to the trunks, which rely on the corresponding service providers to
terminate the call. In this document, the Phone ports and the AA are endpoints. Like the trunks, each
endpoint is represented by a 2-letter abbreviation and a numeral-based instance identifier:
● PH1 = the Phone port (same as PHONE1 port)
● PH2 = the PHONE2 port
● AA1 = the Auto Attendant
Unless stated otherwise, abbreviated endpoint names are case-insensitive. A trunk or an endpoint is
also referred to as a terminal in this document.
The following matrix shows the possible call connections between the endpoints and the trunks.
