Determining The Call Destination - Dialogic DMG1000 User Manual

5.1.3

Determining the Call Destination

The dial plan uses four tables configured by the user to determine the final destination.
• The "Channel Pool" table creates a logical grouping of interfaces and channels that define the
physical interface for the TDM side of the call.
• The "CPID Manipulation" table is used to create a set of formulae used to establish the calling,
called, and redirect numbers for the destination call.
• The "Inbound VoIP Call Routing" table provides a set of rules used to determine the route of
incoming VoIP calls.
The "Inbound TDM Call Routing" table provides a set of rules used to determine the route of
•
incoming TDM calls.
As a call enters the gateway, the incoming characteristics of the call are matched against the dial
plan rules in the appropriate routing table from top down. If a match is found, the CPID
information is updated based on the CPID manipulation entry in the table assigned to the matched
rule. The call is then sent to the destination assigned in the table. Figure 18 below shows call
routing flow for dial plan.
