User's Manual 23. Routing

Call Forking: If the Tel-to-IP Call Forking feature is enabled, the device can send a
Tel call to multiple IP destinations. An incoming Tel call with multiple matched routing
rules (e.g., all with the same source prefix numbers) can be sent (forked) to multiple IP
destinations if the rules are defined with a Forking Group in the table. The call is
established with the first IP destination that answers the call.

Call Restriction: Rejects calls whose matching routing rule is configured with the
destination IP address of 0.0.0.0.

Always Use Routing Table: Even if a proxy server is used, the SIP Request-URI
host name in the outgoing INVITE message is obtained from this table. Using this
feature, you can assign a different SIP URI host name for different called and/or
calling numbers. This feature is enabled using the AlwaysUseRouteTable parameter.

IP Profiles: IP Profiles can be assigned to destination addresses (also when a proxy
is used).

Alternative Routing (when a proxy isn't used): An alternative IP destination can be
configured for a specific call. To associate an alternative IP address to a called
telephone number prefix, assign it with an additional entry with a different IP address,
or use an FQDN that resolves into two IP addresses. For more information on
alternative routing, see 'Alternative Routing for Tel-to-IP Calls' on page
268 .
Notes:
•
The maximum number of alternative routing rules that can be configured for each
routing rule in the table is three.
•
Outbound IP routing can be performed before or after number manipulation. This
is configured using the RouteModeTel2IP parameter, as described below.
•
The Tel to IP Routing can also be configured using the table ini file parameter,
Prefix.

