OBi Call Routing and Digit Map
Trunks, Endpoints, and Terminals
An OBi device is a Voice Service Bridge (VSB) that supports multiple voice services. It can bridge calls across any of the
supported services. By a call bridge we refer to a voice connection connecting two calls on the same or different voice
services. An OBi allows 4 concurrent independent call bridges. The following matrix shows the possible call bridge
connections on an OBi.

Note: Highlighted services may not be available on some models and/or require additional accessories.
Each supported service is also referred to as a trunk (a traditional telco term for a physical wire or wires that deliver phone
services to homes or businesses). Each trunk is represented with 2-letter abbreviation and a 1-based instance identifier:
- SP1 = the SP1 Voice Service (with ITSP A, B, C, or D)
- SP2 = the SP2 Voice Service (with ITSP A, B, C, or D)
- SP3 = the SP3 Voice Service (with ITSP A, B, C, or D)
- SP4 = the SP4 Voice Service (with ITSP A, B, C, or D)
- PP1 = the OBiTALK Service
- LI1 = the PSTN Line Service on the LINE port
- BT1 = OBiBlueTooth 1 Service
- BT2 = OBiBlueTooth 2 Service
The instance identifier may be omitted if it is equal to 1; hence LI is equivalent LI1, PP is equivalent to PP1, etc. These short-
hand notations are used heavily in configuring the OBi device, as found in call routes, call forward numbers, and speed dials
parameters. Unless stated otherwise, the abbreviated trunk names are case insensitive.
In addition to all the call bridging functionalities, each OBi has one or two built-in physical PHONE ports for hooking up
analog telephones or FAX machines. The OBi includes a set of features to support its PHONE ports to make it work also as a
full-featured ATA device. Users can place and receive calls on the PHONE ports over any of the trunks.
The OBi 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 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 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 ports and the AA as endpoints. Like the trunks, each endpoint is represented by a 2-letter abbreviation and a 1-
based instance identifier:
