Introducing MultiVoice Gateway concepts
What is MultiVoice for the MAX?
MultiVoice Gateway for the MAX— User’s Guide Preliminary November 23, 1998 1-7
Since one DSP can only process one call at a time, the Gatekeeper will attempt to assign calls
to each MultiVoice Gateway based upon DSP availability, alternating call assignments
between covering Gateways.
In this figure, the Gatekeeper, having already routed a call from Caller A to Caller D through
MultiVoice Gateway 2, determined that the call from Caller C to Caller B should be routed
through MultiVoice Gateway 3 instead of MultiVoice Gateway 2; to keep the call volume
balanced.
How overlapping coverage areas work
The MultiVoice Access Manager allows you to assign the same Inclusion Areas, defined by
country codes, area codes, country code/area code combinations, area code/exchange
combinations or complete telephone numbers, and so forth, to two or more MultiVoice
Gateways, creating overlapping coverage areas.
How calls are assigned to a MultiVoice Gateway
When a call request is received from a MultiVoice Gateway, the MVAM first identifies all the
MultiVoice Gateways that could be used to complete the call. The MVAM then assigns calls
applying the following criteria:
• Assign the call to the MultiVoice Gateway that has the closest (longest number) match
between the called number and the Inclusion Area.
• Assign subsequent calls for that Inclusion Area to the next MultiVoice Gateway which
services that Inclusion Area.
Suppose the Gatekeeper receives a request from a MultiVoice Gateway to connect a call to
516-555-1111, and the Gatekeeper then identifies two registered MultiVoice Gateways whose
coverage areas include 516-555 and 516-555-11, respectively, as Inclusion Areas. The
Gatekeeper attempts to connect the call through the MultiVoice Gateway with the 516-555-11
Inclusion Area.
If both MultiVoice Gateways have 516-555-11 as an Inclusion Area, the Gatekeeper assigns
the call to the first MultiVoice Gateway it located, then connects the next call for that Inclusion
Area through the next MultiVoice Gateway.
Note: If the call is rejected by the selected MultiVoice Gateway, the call is dropped.
