Routing Table
5.2 Router Configuration
The Router Configuration manages the configuration of the Routing Table for the gateway. The
Routing Table defines how all telephony requests are routed through the gateway between
networks. It also defines the call-party information manipulation rules for passing call-party
information between networks. TDM Trunk Groups and VoIP Host Groups should be created first,
as they are referenced by both the Inbound TDM and Inbound VoIP routing rules.
The Web interface is used for configuring all 4 tables of the Routing Table. New rules can be
added, existing rules can be modified, and existing rules can be deleted.
Note: Changes will not be permanent until the “Submit” button is clicked.
5.2.1 Determining the Call Destination
The Routing Table uses four tables configured by the user to determine the final destination.
• The Inbound TDM Rules Table provides a set of rules used to determine the route of incoming
TDM calls.
• The Inbound VoIP Rules Table provides a set of rules used to determine the route of incoming
VoIP calls.
• The TDM Trunk Groups Table is used to divide the TDM ports and channels into groups that
can be used for matching inbound TDM calls or routing outbound TDM calls.
• The VoIP Host Groups Table is used to divide the VoIP endpoint IP Addresses into groups that
can be used for routing outbound VoIP calls.
Note: The VoIP Host Groups Table is not used for Inbound VoIP call matching.
As a call enters the gateway, the incoming characteristics of the call are matched against the
Routing Table 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.
