This chapter contains commands to configure and maintain Cisco Unified Communications Manager Express (formally known as Cisco Unified CallManager Express). The commands are presented in alphabetical order. Some commands required for configuring Cisco Unified Communications Manager Express (Cisco Unified CME) may be found in other Cisco IOS references. Use the reference master index or search online to find these commands.

outbound-proxy system

To specify that all Cisco Unified Communications Manager Express (Cisco Unified CME) line-side phones connected to a Cisco IOS voice gateway use the global settings for forwarding Session Initiation Protocol (SIP) messages to an outbound proxy, use the outbound-proxy system command in voice register global configuration mode. To disable the SIP outbound proxy function for Cisco Unified CME line-side SIP phones, use the no form of this command.

no outbound-proxy system

Syntax Description

This command has no arguments or keywords.

Command Default

The SIP outbound proxy function for all SIP line-side phones in Cisco Unified CME is enabled and behavior is determined by the global setting on the Cisco IOS gateway.

Command Modes

Voice register global configuration (config-register-global)

Command History

Cisco IOS Release	Cisco Product	Modification
12.4(15)XZ	Cisco Unified CME 4.3 Cisco Unified SIP SRST 4.3	This command was introduced.

Usage Guidelines

If global configuration for outbound proxy is enabled on the Cisco IOS voice gateway and Cisco Unified CME receives a call, Cisco Unified CME forwards all SIP messages to the outbound proxy causing incoming calls to line-side SIP phones to fail. This is the default behavior.

To avoid these failed calls, use the no form of this command in voice register global configuration mode to override global outbound proxy settings for the gateway and disable the outbound proxy function for all line-side SIP phones connected to Cisco Unified CME.

To configure outbound proxy settings for an individual dial peer on the gateway, use the voice-class sip outbound-proxy command in dial peer voice configuration mode.

Examples

The following example shows how to disable the global outbound proxy feature for all line-side SIP phones on a Cisco Unified CME:

Router> enable

Router# configure terminal

Router(config)# voice register global

Router(config-register-global)# no outbound-proxy
