How to Configure Optional Features

The following sections describe how to configure these optional features:

•Enabling Three-Party G.711 Ad Hoc Conferencing

•Defining XML API Schema

Enabling Three-Party G.711 Ad Hoc Conferencing

Enabling three-party G.711 ad hoc conferencing involves configuring the maximum number of simultaneous three-party conferences supported by the Cisco Unified SRST router. For conferencing to be available, an IP phone must have a minimum of two lines connected to one or more buttons. See the "Configuring a Secondary Dial Tone" section on page 70.

SUMMARY STEPS

1. call-manager-fallback

2. max-conferences max-conference-numbers

3. exit

DETAILED STEPS

	Command or Action	Purpose
Step 1	call-manager-fallback Example: Router(config)# call-manager-fallback	Enters call-manager-fallback configuration mode.
Step 2	max-conferences max-conference-numbers Example: Router(config-cm-fallback)# max-conferences 16	Sets the maximum number of simultaneous three-party conferences supported by the router. The maximum number possible is platform dependent: •Cisco 1751 router:8 •Cisco 1760 router:8 •Cisco 2600 series routers:8 •Cisco 2600-XM series routers:8 •Cisco 2801 router:8 •Cisco 2811, Cisco 2821, and Cisco 2851 routers:16 •Cisco 3640 and Cisco 3640A routers:8 •Cisco 3660 router: 16 •Cisco 3725 router: 16 •Cisco 3745 router: 16 •Cisco 3800 series router: 24
Step 3	exit Example: Router(config-cm-fallback)# exit	Exits call-manager-fallback configuration mode.

Examples

The following example configures up to eight simultaneous three-way conferences on a router.

call-manager-fallback

 max-conferences 8

Defining XML API Schema

The Cisco IOS commands in this section allow you to specify parameters associated with the XML API. For more information, see the XML Provisioning Guide for Cisco CME/SRST. See the "Configuring Cisco Unified SRST MOH Live-Feed Support (Optional)" section on page 143 for configuration instructions.

SUMMARY STEPS

1. call-manager-fallback

2. xmlschema schema-url

3. exit

DETAILED STEPS

	Command or Action	Purpose
Step 1	call-manager-fallback Example: Router(config)# call-manager-fallback	Enters call-manager-fallback configuration mode.
Step 2	xmlschema schema-url Example: Router(config-cm-fallback)# xmlschema http://server2.example.com/ schema/schema1.xsd	Specifies the URL for an XML API schema to be used with this Cisco Unified SRST system. •schema-url: Local or remote URL as defined in RFC 2396.
Step 3	exit Example: Router(config-cm-fallback)# exit	Exits call-manager-fallback configuration mode.
