Table 5-3: Tel to IP Routing Table

Parameter

Description

Any telephone number whose destination number matches the prefix defined in the ‘Destination Phone Prefix’ field and its source number matches the prefix defined in the adjacent ‘Source Phone Prefix‘ field, is sent to the IP address entered in the ‘IP Address’ field.

Note that Tel to IP routing can be performed according to a combination of source and destination phone prefixes, or using each independently.

Note 1: An additional entry of the same prefixes can be assigned to enable alternative routing.

Note 2: For available notations that represent multiple numbers, refer to Section 5.8.3.1 on page 47.

Destination IP Address	In each of the IP Address fields, enter the IP address that is assigned to these
	prefixes. Domain names, such as domain.com, can be used instead of IP addresses.
	To discard outgoing IP calls, enter 0.0.0.0 in this field.
	Note: When using domain names, you must enter a DNS server IP address, or
	alternatively define these names in the ‘Internal DNS Table’.
Profile ID	Enter the number of the IP profile that is assigned to the destination IP address
	defined in the ‘Destination IP Address’ field.
Status	A read only field representing the quality of service of the destination IP address.
	N/A = Alternative Routing feature is disabled.
	OK = IP route is available
	Ping Error = No ping to IP destination, route is not available
	QoS Low = Bad QoS of IP destination, route is not available
	DNS Error = No DNS resolution (only when domain name is used instead of an IP
	address).

5.8.4.2IP to Trunk Group Routing Table

The IP to Trunk Group Routing Table is used to route incoming IP calls to groups of E1/T1 B-channels called trunk groups. Calls are assigned to trunk groups according to any combination of the following three options (or using each independently):

•Destination phone prefix

•Source phone prefix

•Source IP address

The call is then sent to the VoIP gateway channels assigned to that trunk group. The specific channel, within a trunk group, that is assigned to accept the call is determined according to the trunk group’s channel selection mode which is defined in the Trunk Group Settings table

(Section5.8.7 on page 60), or according to the global parameter ‘ChannelSelectMode’ (refer to Table 6-5on page 115).

Note: When a release reason that is defined in the ‘Reasons for Alternative IP to Tel Routing’ table is received for a specific IP Tel call, an alternative trunk group for that call is available. To associate an alternative trunk group to an incoming IP call, assign it with an additional entry in the ‘IP to Trunk Group Routing’ table (repeat the same routing rules with a different trunk group ID).

For detailed information on the ‘Reasons for Alternative Routing Tables’, refer to Section 5.8.4.4 on page 54.

To use trunk groups you must also do the following:

•You must assign a trunk group ID to the VoIP gateway E1/T1 B-channels on the Trunk Group Table. For information on how to assign a trunk group ID to a B-channel, refer to Section 5.8.6 on page 58.
