22.3 Configuring IP to Hunt Group Routing Table
The IP to Hunt Group Routing Table page allows you to configure up to 24 inbound call
routing rules:
For IP-to-Tel routing: This table is used to route incoming IP calls to Hunt Groups. The
specific channel pertaining to the Hunt Group to which the call is routed is determined
according to the Hunt Group's channel selection mode. The channel selection mode
can be defined per Hunt Group (see 'Configuring Hunt Group Settings' on page
204
)
or for all Hunt Groups using the global parameter ChannelSelectMode.
The IP to Hunt Group Routing Table provides two configuration areas:
Matching characteristics of incoming IP call, for example, prefix of destination number.
Operation (destination), for example, sends to a specific Hunt Group.
If the incoming call matches the characteristics of a rule, then the call is sent to the
destination configured for that rule.
The device also supports alternative routing if the Hunt Group is unavailable:
If a call release reason is received for a specific IP-to-Tel call and this reason is
configured for alternative IP-to-Tel routing, then the device re-routes the call to an
alternative Hunt Group. The alternative route is configured in this table as an
additional row (below the main routing rule) with the same call characteristics, but with
a destination to a different Hunt Group. For more information on IP-to-Tel alternative
routing, see 'Alternative Routing to Trunk upon Q.931 Call Release Cause Code' on
page
237
.
The device can re-route (i.e., call redirection) IP-to-Tel calls to an alternative IP
destination using SIP 3xx responses. For more information, see 'Alternative Routing to
IP Destinations upon Busy Trunk' on page
238
.
The device automatically re-routes an IP-to-Tel call to a different physical FXO port if the
initially destined FXO port within the same Hunt Group is detected as out of service (e.g.,
physically disconnected). When the physical FXO port is disconnected, the device sends
the SNMP trap, GWAPP_TRAP_BUSYOUT_LINK notifying of the out-of-service state for
the specific FXO line. When the FXO port is physically reconnected, this trap is sent
notifying of the back-to-service state.
Note:
You can also configure the IP to Hunt Group Routing Table using the table ini
file parameter, PSTNPrefix (see 'Number Manipulation Parameters' on page
564
).
To configure IP-to-Tel routing rules:
1.
Open the IP to Hunt Group Routing Table page (
