The OBi110 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 may be routed to the AA which then offers a menu of options to the caller to direct
it further. It could be directed to the PHONE port, or bridged with another call on a trunk (which the AA “dials” or sets up on
behalf of the caller).
The PHONE port and the AA are the two entities in the OBi device that calls can terminate (i.e., starts or ends there), as
opposed to the trunks, which rely on the corresponding service providers to terminate the call. In this document we refer to
the PHONE port and the AA as
endpoints . Like the trunks, each endpoint is represented by a 2-letter abbreviation and a 1-
based instance identifier:
- PH1 = the PHONE Port (same as PHONE1 port)
- PH2 = the PHONE2 Port
5
- 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:

Call Routing – The OBi Way
Call Routing is the process by which the OBi Device sets up a call bridge or a (endpoint) call based on such information as:
the trunk on which the call originates, the caller’s number, the called number, etc. Call Routing Rules are parameters used
to instruct the OBI device how to route calls. A call may transform into a call bridge or an endpoint call after being routed by
the OBi according to the given routing rules.
Every call has to be originated from somewhere. From the device’s perspective, calls originated from the trunk side are
considered Inbound Calls, while calls originated from an endpoint Outbound Calls. The call routing rule syntaxes for
inbound calls and outbound calls are slightly different and we shall explain them separately below. Call Routing Rule
configuration relies heaving on digit maps. If you are not familiar with how digit map works yet, please read the
Digit Map
Configuration Section in this document first.
