25.2 Configuring Tel-to-IP Routing Rules
The Tel-to-IP Routing table lets you configure up to 180 Tel-to-IP routing rules. Tel-to-IP
routing rules are used to route calls from the Tel side to an IP destination.
Configuration of Tel-to-IP routing rules includes two areas:

Rule: Defines the characteristics of the incoming Tel call (e.g., Trunk Group on which
the call is received).

Action: Defines the action that is done if the incoming call matches the characteristics
of the rule (i.e., routes the call to the specified IP destination).
The device searches the table from top to bottom for the first rule that matches the
characteristics of the incoming call. If it finds a matching rule, it sends the call to the IP
destination configured for that rule. If it doesn't find a matching rule, it rejects the call.
You can configure the routing rule with one or more of the following incoming Tel
characteristics:

Source Trunk Group (from where the call is received)

Source (calling) and destination (called) telephone number prefix and suffix
You can configure the IP destination to one of the following:

IP address.

FQDN.

E.164 Telephone Number Mapping (ENUM service).

Lightweight Directory Access Protocol (LDAP). For more information, see LDAP-
based Management and SIP Services on page
246 and Active Directory-based
Routing for Microsoft Lync on page 266.

IP Group. When an IP Group is selected, the device sends the call to the IP address
configured for the Proxy Set that is associated with the IP Group (configured in
''Configuring IP Groups'' on page
343). The SRD associated with the IP Group
determines the:
• SIP Interface (SIP port and control network interface) - important when using
multiple SIP control VLANs
• Media Realm (port and network interface for media / RTP voice)
• SRD-related features on which the call is routed
If you configure the routing rule to send the call to any destination other than an IP Group
(e.g., an IP address), you need to select a SIP Interface for the call. If no SIP Interface is
selected, the device uses the SIP Interface associated with the default SRD (Index 0). If
you have deleted this SRD or SIP Interface, for whatever reason, the device drops the call.
The SIP Interface determines many attributes for the destination:

Device's logical SIP port and network interface through which the call signaling is sent

Device's logical RTP port and network interface through which the media is sent
(Media Realm)

Other features that can be configured for the SIP Interface
