Feature Summary

Table 1 contains a description of SCCP Meet-Me Conference in Cisco IOS Release 12.4(9th)T, along with information about how to configure support your Cisco call-control system.

Table 1 SCCP Meet-Me Conference Feature Summary 

Feature	How Phone User Accesses Feature	Configuration on Call-Control System
SCCP Meet-Me Conference Enables user on an analog SCCP phone to start or join a meet-me conference call.	To start a meet-me conference, user dials feature access code (FAC) prefix and meet-me conference code, and following the confirmation tone, the meet-me conference number. Default prefix and code is **5. Participants can join the conference by dialing the meet-me conference number. Participants hear a busy tone if they call the conference number before the conference controller has joined. In this case, participants must call back. To end a meet-me conference, all participants must hang up.The conference does not automatically end when the conference controller disconnects. Before a conference controller can start a meet-me conference, meet-me conference numbers must be configured in your Cisco call-control system by the system administrator. Note The stcapp feature access-code command must be enabled on the Cisco IOS gateway.	Cisco Unified Communications Manager To configure: •See the "Conference Bridge Configuration" section of the "Media Resource Configuration" chapter in the appropriate Cisco Unified Communications Manager Administration Guide. •See the "Meet-Me Number/Pattern Configuration" section of the "Call Routing" chapter in the appropriate Cisco Unified Communications Manager Administration Guide. Cisco Unified CME To configure meet-me conferencing and meet-me conference numbers, see "SCCP: Configuring Conferencing" in the Cisco Unified CME Administrator Guide.

SCCP Meet-Me Conference

Meet-me conferencing is hardware-based conferencing. Hardware-based conferencing uses digital signal processors (DSPs) to allow more parties than software-based ad hoc conferencing, which is limited to only three parties. Meet-me conferencing requires a range of meet-me conference numbers that are created in the Cisco call-control system and allocated for exclusive use of the conference.

To start an SCCP Meet-Me Conference on an analog phone connected to a voice gateway, you must dial a feature access code (FAC) consisting of a prefix plus a feature code. The default FAC for SCCP Meet-Me Conference is **5.

When you start a meet-me conference, the Cisco call-control system considers you the conference controller. When a meet-me conference is set up, you choose a meet-me conference number and advertise it to conference participants. Participants call the number to join the conference. Anyone who calls the number while the conference is active joins the conference as long as the number of participants does not exceed the maximum number of parties specified for the conference type and sufficient streams are available on the conference device.

For example, the conference shown in Figure 1 is created when the conference controller at extension 1215 presses the FAC for SCCP Meet-Me Conference, hears a confirmation tone, and then dials the meet-me conference number 1500. Extension 1225 and extension 1235 join the meet-me conference by dialing 1500. Extensions 1215, 1225, and 1235 are all parties in a meet-me conference on extension 1500.

Figure 1 Simple Meet-Me Conference Graphic to be inserted HERE

If other phone users press the meet-me FAC and then dial the same meet-me conference number, the Cisco call-control system ignores the signals.

A meet-me conference continues even if the conference controller hangs up.

If only one participant remains in the meet-me conference, for example, if one participant forgets to hang up, the conference call is disconnected after five minutes to free system resources.

If the conference controller is waiting for participants to join the conference and is the only party on the conference, the conference is not disconnected because significant resources are not being used.

How to Configure SCCP Meet-Me Conference

To enable feature access codes (FACs), define a prefix other than the default (**), and define a feature code other than the default (5) for SCCP Meet-Me Conference, perform the following steps.

DETAILED STEPS

	Command or Action	Purpose
Step 1	enable Example: Router> enable	Enables privileged EXEC mode. •Enter your password if prompted.
Step 2	configure terminal Example: Router# configure terminal	Enters global configuration mode.
Step 3	stcapp feature access-code Example: Router(config)# stcapp feature access-code	Enables feature access codes (FACs) in the STC application and enters the STC application feature access-code configuration mode.
Step 4	prefix prefix-string Example: Router(stcapp-fac)# prefix *#	(Optional) Sets a prefix string to indicate that the following keypad character is a feature access code. •prefix-string—String of one to five characters that can be dialed on a telephone keypad. String must start with an asterisk (*) or a number sign (#). Default is **. Note Configuring the prefix command changes the prefix for all FACs. For information about FACs for other features, see SCCP Controlled Analog (FXS) Ports with Supplementary Features in Cisco IOS Gateways.
Step 5	meetme-conference keypad-character Example: Router(stcapp-fac)# meetme-conference #55	(Optional) Sets the code to use for enabling meet-me conferencing on FXS ports. •keypad-character—Character string that can be dialed on a telephone keypad. Default is 5. •Length of keypad-character is a single character (0-9, *, #) or two digits (00-99) or To configure the code so that the analog phone user is not required to dial the prefix to access this feature, length is 2-4 characters and the leading or ending character of the string must be an asterisk (*) or a number sign (#).
Step 6	end Example: Router(stcapp-fac)# end	Exits to privileged EXEC mode.

Examples

The following partial output from the show running configuration command shows that FACs are enabled and displays the values for feature codes that have been modified. In this configuration, because the feature code for SCCP Meet-Me Conference is at least two characters long (#55) and begins with a number sign (#), phones users are not required to dial the FAC prefix to access the Meet-Me Conference feature. A conference controller must dial only #55 and following the confirmation tone, the meet-me conference number to create a meet-me conference call.

•meetme-conference

meetme-conference

To define a feature code for a Feature Access Code (FAC) to initiate an SCCP Meet-Me Conference, use the meetme-conference command in STC application feature access-code configuration mode. To return the feature code to its default, use the no form of this command.

meetme-conference keypad-character

no meetme-conference

Syntax Description

keypad-character

Character string that can be dialed on a telephone keypad (0-9, *, #). Default: 5. The string can be any of the following: •A single character (0-9, *, #) •Two digits (00-99) •Two to four characters (0-9, *, #) and the leading or ending character must be an asterisk (*) or number sign (#)

Command Default

The default value of the feature code is 5.

Command Modes

STC application feature access-code configuration (config-stcapp-fac)

Command History

Release	Modification
12.4(20)YA	This command was introduced.

Usage Guidelines

This command changes the value of the feature code for SCCP Meet-Me Conference from the default (5) to the specified value.

If the length of the keypad-character argument is at least two characters and the leading or ending character of the string is an asterisk (*) or a number sign (#), phone users are not required to dial a prefix to access this feature. Typically, phone users dial a special feature access code (FAC) consisting of a prefix plus a feature code, for example **2. If the feature code is 55#, the phone user dials only 55#, without the FAC prefix, to access the corresponding feature.

If you attempt to configure this command with a value that is already configured for another FAC, speed-dial code, or the Redial FSD, you receive a message. If you configure a duplicate code, the system implements the first matching feature in the order of precedence shown in the output of the show stcapp feature codes command.

If you attempt to configure this command with a value that precludes or is precluded by another FAC, speed-dial code, or the Redial FSD, you receive a message. If you configure a feature code to a value that precludes or is precluded by another code, the system always executes the call feature with the shortest code and ignores the longer code. For example, #1 will always preclude #12 and #123. You must configure a new value for the precluded code in order to enable phone user access to that feature.

To display a list of all FACs, use the show stcapp feature codes command.

Examples

The following example shows how to change the value of the feature code for SCCP Meet-Me Conference from the default (5). This configuration also changes the value of the prefix for all FACs from the default (**) to ##. With this configuration, a phone user must press ##9 on the phone keypad to cancel all-call forwarding.

Router(config)# stcapp feature access-code

Router(config-stcapp-fac)# prefix ##

Router(config-stcapp-fac)# meetme-conference 9

Router(config-stcapp-fac)# exit
