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. The OBi110 allows 4 concurrent independent call bridges. The following matrix shows the possible call bridge
connections on the OBi110:

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
2
, or D
2
)
- SP2 = the SP2 Voice Service (with ITSP A, B, C
2
, or D
2
)
- SP3 = the SP3 Voice Service (with ITSP A, B, C
2
, or D
2
)
- SP4 = the SP4 Voice Service (with ITSP A, B, C
2
, or D
2
)
- PP1 = the OBiTALK Service
- LI1
1
= the PSTN Line Service on the LINE port
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, the OBi110 has a built-in physical PHONE port for hooking up analog
telephones or FAX machines. OBi110 includes a set of features to support its PHONE port to make it work also as a full-
featured ATA device. Users can place and receive calls on the PHONE port over any of the trunks.
