Call routing rules:
• Outgoing IP calls (IP-to-IP or Tel-to-IP): The IP Group identifies the source of the
call and is used as the destination of the outgoing IP call (defined in the
Outbound IP Routing Table). For Tel-to-IP calls, the IP Group (Serving IP Group)
can be used as the IP destination to where all SIP dialogs that are initiated from a
Trunk Group are sent (defined in Configuring Hunt Group Settings on page 297).
• Incoming IP calls (IP-to-IP or IP-to-Tel): The IP Group identifies the source of the
IP call.
• Number Manipulation rules to IP: The IP Group is used to associate the rule with
specific calls identified by IP Group.
Notes:
• IP Group ID 0 cannot be used. This IP Group is set to default values and
is used by the device when IP Groups are not implemented.
• When operating with multiple IP Groups, the default Proxy server must
not be used (i.e., the parameter IsProxyUsed must be set to 0).
• If different SRDs are configured in the IP Group and Proxy Set tables,
the SRD defined for the Proxy Set takes precedence.
• You can also configure the IP Groups table using the table ini file
parameter, IPGroup (see 'Configuration Parameters Reference' on page
755) or CLI command, configure voip > control- network ip-group.
To configure IP Groups:
1. Open the IP Group Table page (Configuration tab > VoIP menu > Control Network
submenu > IP Group Table).
2. Click the Add button: the following dialog box appears:

5. To save the changes to flash memory, see 'Saving Configuration' on page 624.
