Prerequisites for Configuring an Inbound Dial Peer to Match on a URI

• Enable SIP header passing. For information, see the Cisco IOS SIP Configuration Guide, Release 15.1
• Write a Tcl IVR 2.0 script or VoiceXML document that accepts a SIP or TEL URI. For information, see the Tcl IVR API Version 2.0 Programmer's Guide or Cisco VoiceXML Programmer's Guide.

Cisco Unified Border Element

Cisco IOS Release 15.1(2)T or a later release must be installed and running on your Cisco Unified Border Element.

Cisco Unified Border Element (Enterprise)

Cisco IOS XE Release 3.6S or a later release must be installed and running on your Cisco Unified Border Element (Enterprise).

Configuring an Inbound Dial-Peer to Match the URI on SIP Calls

This task describes how to configure an inbound dial-peer to match the URI in a SIP call.

SUMMARY STEPS

1.    enable


2.    configureterminal


3.    voice class uritag


4.    host hostname-pattern or host {host {ipv4: ipv4-address | ipv6:ipv6-address |dns:dns-address |hostname-pattern }

5.    exit


6.    dial-peer voice tagvoip


7.    sessionprotocol sipv2


8.    incoming uri { from | request | to | via tag


9.    end

DETAILED STEPS

	Command or Action	Purpose
Step 1	enable Example: Device> enable	Enables privileged EXEC mode. Enter your password if prompted.
Step 2	configureterminal Example: Device> configure terminal	Enters global configuration mode.
Step 3	voice class uritag Example: Device(config)# voice class uri ab200 sip	Creates a voice class for matching dial peers to a SIP and enters voice URI class configuration mode.
Step 4	host hostname-pattern or host {host {ipv4: ipv4-address | ipv6:ipv6-address |dns:dns-address |hostname-pattern } Example: Device(config-voice-uri-class)# host server1 or Device(config-voice-uri-class)# host ipv4:10.0.0.0	(Optional) Specifies a regular expression pattern for matching the hostname field in the SIP URI. This command can have a single instance only. You can specify up to ten instances of this command. Note    You can use either the host hostname or host {host {ipv4: ipv4-address | ipv6:ipv6-address |dns:dns-address |hostname-pattern } command.
Step 5	exit Example: Device(config-voice-uri-class)# exit	Enters global configuration mode.
Step 6	dial-peer voice tagvoip Example: Device(config)# dial-peer voice 6000 voip	Enters dial peer voice configuration mode.
Step 7	sessionprotocol sipv2 Example: Device(config-dial-peer)# session protocol sipv2	Configures SIP as the session protocol type.
Step 8	incoming uri { from | request | to | via tag Example: Device(config-dial-peer)# incoming uri via ab200	Specifies the voice class used to match a VoIP dial peer to the URI of an incoming call.
Step 9	end Example: Device(config-dial-peer)# end	Exits dial peer voice configuration mode and enters privileged EXEC mode.

Feature Name	Releases	Feature Information
Inbound Dial-peer Match Based on Remote IP Address on SIP Trunks	15.1(2)T	The Support Inbound Dial-peer Match Based on Remote IP Address on SIP Trunks feature supports the expansion of inbound dial-peer matching logic to include matching based on the source IP address of inbound signaling on a SIP trunk. This feature enables enforcement of specific call-treatment, security, and routing policies on each SIP trunk. In Cisco IOS Release 15.1(2)T this feature was implemented on the Cisco Unified Border Element. The following commands were introduced or modified: dial-peer voice, voice-class uri.
SIP and TEL URL support	Cisco IOS XE Release 3.6S Cisco IOS XE Release 3.8S	The Support Inbound Dial-peer Match Based on Remote IP Address on SIP Trunks feature supports the expansion of inbound dial-peer matching logic to include matching based on the source IP address of inbound signaling on a SIP trunk. This feature enables enforcement of specific call-treatment, security, and routing policies on each SIP trunk. In Cisco IOS Release 15.1(2)T this feature was implemented on the Cisco Unified Border Element (Enterprise). The following commands were introduced or modified: dial-peer voice, voice-class uri.
