■ The Forking Group members must be configured in a table row
that is immediately below the main Forking routing rule, or below
an alternative routing rule for the main rule, if configured.
■ For IP-to-IP alternative routing, configure alternative routing
reasons upon receipt of 4xx, 5xx, and 6xx SIP responses (see
Configuring SIP Response Codes for Alternative Routing
Reasons). However, if no response, ICMP, or a SIP 408
response is received, the device attempts to use the alternative
route even if no entries are configured in the Alternative Routing
Reasons table.
■ Multiple alternative route entries can be configured (e.g., Index 1
is the main route - Route Row - and indices 2 through 4 are
configured as alternative routes).
Defines the IP Group from where the IP call is received (i.e., the IP
Group that sent the SIP dialog). Typically, the IP Group of an
incoming SIP dialog is determined (or classified) using the
Classification table (see
The default is Any (i.e., any IP Group).
Note: The selectable IP Group for the parameter depends on the
assigned Routing Policy (in the 'Routing Policy' parameter in this
table). For more information, see
Rules.
Defines the SIP dialog request type (SIP Method) of the incoming
SIP dialog.
■ [0] All (default)
■ [1] INVITE
■ [2] REGISTER
■ [3] SUBSCRIBE
■ [4] INVITE and REGISTER
■ [5] INVITE and SUBSCRIBE
■ [6] OPTIONS
Note:
■ For User-type IP Groups, if you also need to send REGISTER
messages received from this IP Group, then it is highly
recommended that the configured destination of the routing rule
is a Server-type IP Group and not an IP address (configured by
the 'Destination Type' parameter). If you need to send non-
REGISTER messages (e.g., INVITE) to a destination that is
configured as an IP address, then you need to configure two IP-
to-IP Routing rules for this User-type IP Group, one for routing
REGISTER messages and one for routing non-REGISTER
messages.
■ If the device receives a REFER message, it searches again for
a matching routing rule in the IP-to-IP Routing table and then
forwards the message to the destination configured of the
matched rule.
