5.2 CPID (Number) Matching
Part of the criteria for matching the characteristics of an incoming call to a rule in one of the dial
plan routing tables is number matching. The incoming calling or called number is tested against a
match rule defined in the routing table. If the match fails, this routing rule table entry will fail.
The formula for number matching gets entered via the dial plan configuration in the "Inbound VoIP
Call Routing" Web page and the "Inbound TDM Call Routing" Web page. Table 2 shows the syntax
used for number matching. The example shows an attempted match with the following number…

5.3 Channel Pools
5.3.1 Description
A channel pool is a logical grouping of interfaces and channels that define the physical interface
for the TDM side of the call. All incoming TDM calls arrive on a physical interface and a channel.
A channel pool is a way of identifying the interface / channel combination. Outgoing calls are
made to a physical interface and a channel. For some calls, it may be necessary to select the
specific interface and channel from a group of possible options. A channel pool defines how this is
selected.
5.3.2 TDM Interface Types
The gateway supports multiple types of TDM interfaces. The number of physical interfaces and
channels supported vary. Table 3 shows the possibilities:
