Parameter Description
Destination IP Address
In each of the IP Address fields, enter the IP address (and optionally port number)
that is assigned to these prefixes. Domain names, such as domain.com, can be
used instead of IP addresses.
For example: <IP Address>:<Port>
To discard outgoing IP calls, enter 0.0.0.0 in this field.
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).
IP 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
(See
Configuring the Trunk Group Settings
), or according to the global parameter
‘ChannelSelectMode’ (see
Table 44
).
When a release reason that is defined in the ‘Reasons for Alternative IP to Tel
Routing’ table is received for a specific IP
Æ
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’, see
Reasons for Alternative Routing
.
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, see
Configuring the Trunk Group Table
.
You can configure the Trunk Group Settings table to determine the method in which new
calls are assigned to channels within the trunk groups (a different method for each trunk
