Call Management Features - Quintum Tenor BX Product Manual

Hunt Local Directory Numbers. A Hunt Local Directory Number (Hunt LDN) is a phone number
reachable through local Line Circuits.
Hop-Off Directory Number. A Hop-off PBX call travels over IP, and then "hops" off into the pub-
lic network (PSTN) on the distant side to reduce or eliminate public toll charges (also known as
Leaky Area Map). A Hop-Off Directory Number is routed over the IP to another Tenor location and
then out to the Trunk circuit, possibly to the PSTN as a local call.
Static Routes. Static Routes are used between networks and other H.323 devices that are not regis-
tered to the network through the Border Element (such as non-Quintum gateways). A static route
associates endpoints (as represented by their IP address (as represented by their IP address) with
Directory Number patterns.

Call Management Features

Dynamic Call Routing. Tenor BX's intelligent call routing capabilities are state-of-the-art. The unit
automatically detects and supports three call types: voice, fax, and modem.
Tenor BX will first identify the call origination site—trunk circuit, line circuit, or IP routing group
—and then route the call according to any parameters you have configured in the routing database.
Each call may be routed via circuit switched path between any two circuit groups, or compressed
and transported via VoIP when connecting to an IP routing group. Trunk circuits are those that typi-
cally connect to another circuit switched network such as the PSTN. Line circuits typically connect
to a termination device on the user premises, such as a PBX.
Public/Private Dial Plan Support.The Tenor BX supports public and private dial plans. A public
dial plan includes numbers which conform to the international dialing plan (E.164) of a country
code + city/area code + local number. For a public dial plan, you can define the numbering plan
structure for the Tenor BX to use for outgoing calls.
A private dial plan does not conform to a public dialing plan (i.e., 3 digit dialing plan); through the
Tenor BX you are able to configure the unique pattern/dialing plan structure, including number
length.
You are able to configure which dial plan to use for incoming and outgoing calls, including whether
other options such as hop-off calls, will use a public or private dial plan.
User Programmable Dial Plan Support. The User Programmable Dial Plan Support (UPDP)
enables the Tenor to identify a completely customizable set of digit sequences, such as Local,
National, International or Private Numbers.
PassThrough support for certain call types. Certain call types can be directly routed to a trunk
circuit, without going IP. There are several routing tables you can configure via the Configuration
Manager to adjust how the Tenor BX unit routes these types of "pass through" numbers. For exam-
ple, you may want to configure 911 as a "bypass number", which means that all 911 calls coming
into Tenor BX from the line circuit will be routed directly to a Trunk circuit presumably connected to
a PSTN. Bypass calls are never routed over IP.
