Routing Table
Called Party Number - The formula as specified in the section above that determines the called
number of the outgoing call.
Called Party Name - The formula as specified in the section above that determines the called
name of the outgoing call.
Redirecting Party Number - The formula as specified in the section above that determines the
redirect number of the outgoing call.
Redirect Party Name - The formula as specified in the section above that determines the redirect
name of the outgoing call.
Select Primary / Alternate Route
One Primary and multiple Alternate routes may be defined for a given routing rule if the gateway is
unable to route the request to the Primary. The Alternate routes will then be attempted until the
request is successfully routed, or if there are no more Alternate routes to try. Examples of failure
that may occur before the call is connected to the outbound destination include: for SIP, any 4xx,
5xx or 6xx response; for TDM, error tone, congestion tone, special information tone; for any, the
user is busy, the physical interface is unavailable.
Note: The Primary and Alternate routes differ only in the Outbound Routes section. All other parts of the
rule (CPID matching, etc.) are identical between the primary and alternate routes.

5.2.4 TDM Trunk Groups Table
TDM Trunk Groups are logical groupings of ports and channels that define the physical port for the
TDM side of the call. The port is a physical connection to the gateway (i.e. ISDN span, Analog
line), while the channel is a logical connection within the port (i.e. T1 CAS line includes up to 24
channels while an Analog line has a single channel). All incoming TDM calls arrive on a physical
port and a channel. TDM Trunk Groups are a way of identifying the port / channel combination.
For some calls, it may be necessary to select the specific port and channel from a group of possible
options. TDM Trunk Groups define how this is selected.
The configuration of TDM Trunk Groups are used for the routing of requests from/to the TDM
network. TDM Trunk Groups are referenced by Inbound TDM Rules and Inbound VoIP Rules.
TDM Trunk Groups are used to match inbound requests with routing rules and to specify outbound
routes to the TDM network.
