Cisco Unified CME To configure, see "Configuring Conferencing" in the Cisco Unified CME Administration Guide.
Feature Access Codes (FACs) Access features using an abbreviated code. Flexible FACs Allows you to configure feature codes for FACs so that phone users are not required to dial the prefix before dialing the feature code to access an SCCP feature.	User accesses features by dialing a feature access code (FAC), typically consisting of a prefix plus a feature code. For a list of STC application call features that can be accessed by dialing a FAC, see Table 6. Note The stcapp feature access-code command must be enabled on the Cisco voice gateway.	For feature and configuration information for individual STC application call features for which you can configure a FAC, see Table 6.
Redial Dials again the last number dialed from this phone.	User dials the feature speed dial (FSD) prefix and the redial code. Default prefix and code is *#. Note The stcapp feature speed-dial command must be enabled on the Cisco voice gateway.	No configuration tasks required on your Cisco call-control system.
Speed Dial Dials a telephone number using an abbreviated code.	Up to 99 Speed Dials (Local Phone) User dials the FSD prefix and desired speed-dial code. The digit command determines the number of digits used for FSD codes on the Cisco voice gateway. Default prefix and code range is: •*1 to *9 for one-digit codes •*01 to *99 for two-digit codes User stores speed-dial destinations by using the Cisco Unified CME GUI or an administrator stores destinations on the Cisco call-control system.

Call Park Directed Call Pickup Directed Puts a call on hold at a designated extension so that it can be retrieved by anyone.	During an active call, user presses hookflash for dial tone, and then dials the call-park slot number configured on the call-control system. User retrieves the call by dialing the FAC prefix, the directed pickup code, and the call-park slot number where the call was parked. Default prefix and code is **6. For example, if the call is parked at slot 1211, user dials **61211. Users can also retrieve the last call parked by their own extensions by dialing the FAC prefix, the directed pickup code, and an asterisk (*). Default prefix and code is **6*. Note The stcapp feature access-code command must be enabled on the Cisco voice gateway.	Cisco Unified Communications Manager This feature is not supported for Cisco Unified Communications Manager. Cisco Unified CME To configure, see "Configuring Call Coverage Features" in the Cisco Unified CME Administration Guide.
Call Pickup of Ringing Extension, Directed Allows incoming calls to be picked up by phones other than the ringing phone.

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 voice 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 Administration Guide.

Flexible Feature Access Codes

To access certain SCCP telephony control (STC) application call features on analog phones connected to a voice gateway, phone users must dial a feature access code (FAC) consisting of a prefix plus a feature code, for example **1.

The prefix for FACs is a one to five-character string beginning with an asterisk (*) or number sign (#). The default value is **.

Before Cisco IOS Release 12.4(20)YA, feature codes for FACs were limited to a single character (0-9, *, or #). In Cisco IOS Release 12.4(20)YA and later releases, the Flexible Feature Access Code (FAC) feature allows you to configure feature codes as follows:

•For feature codes to be dialed after dialing the prefix, you can configure one character (0-9, *, or #) or two digits (00-99) that can be dialed on phone keypad.

•For feature codes that do not require the prefix to be dialed to access the feature, you can configure two to four characters that can be dialed on phone keypad and the leading or ending character must be an asterisk (*) or number sign (#).

•The default values for specific FACs are listed in Table 6.

Flexible feature access codes allow you to configure feature codes for FACs so that phone users are not required to dial the prefix before dialing the feature code to access an SCCP feature on an analog phone. If you configure a feature code that is at least two characters and the leading or ending character is an asterisk (*) or number sign (#), no prefix is required to access the feature. For example, if you configure a feature code of 78# for Call Forward Cancel, the phone user dials just the feature code (78#) to access that feature. If you configure a feature code of 78 for Call Forward Cancel, the phone user must dial the prefix, whatever it is, plus the feature code (78) to access that feature.

If you attempt to set a feature code to a value that is already configured for another feature code, a speed-dial code, or the Redial FSD, you receive a warning message. If you configure a duplicate code, the system implements the first feature it matches in the order shown in the output of the show stcapp feature codes command. Precedence is determined by the value for each feature code.

If you attempt to set a feature code to a value that precludes or is precluded by another feature code, a speed-dial code, or the Redial FSD, you receive a warning message. For example, if you attempt to set a feature code of #123 and #12 is already configured for another feature, such as Call Forward Cancel, the following message appears:

#123 is precluded by call forward cancel(#12)  
 

Or if you attempt to configure #1 and #12 is already configured for another feature, such as Call Forward Cancel, the following message appears:

#1 precludes call forward cancel(#12) 

These messages will not prevent you from configuring the feature code.

After a phone user dials the FAC or FSD, the system matches the dialed string with configured FACs, Redial, and speed-dial codes in the follow order and executes the first complete match, ignoring the longer feature code:

•Malicious call ID (MCID)

•Call forward all

•Call forward cancel

•Pickup local group

•Pickup different group

•Pickup direct

•Redial

•Speeddial1

•Speeddial2

•Speeddial3

•and so on...

For example, assume that Call Forward All is #123, Call forward Cancel is #12, and Pickup Local Group and Redial are both #1. After the phone user dials #1, the system matches the dialed characters to the configured codes in the order listed and because it is the first exact match, executes Pickup Local Group. If the phone user dials #12, the digit 2 will be ignored because #1 is an exact match and the system executes Pickup Local Group again. In this configuration, the phone user is unable to access Call Forward All (#123), Call Forward Cancel (#12), or Redial (#1) because all are precluded by #1 for Pickup Local Group. You must configure a new value for a precluded feature code in order to enable a FAC for that feature.

To enable and configure FACs on an analog FXS port, see the "Configuring Feature Access Codes" section.

Flexible feature Access Code Support for Redial

Flexible feature access codes includes support for Redial. To access Redial using a feature speed dial (FSD), analog phone users must dial a prefix and speed-dial code. The default prefix and speed-dial code for Redial is *#.

In Cisco IOS Release 12.4(20)YA and later releases, if you configure a speed-dial code for Redial of one or two characters that can be dialed on a phone keypad, the phone user must dial the FSD prefix before dialing the speed-dial code. If you configure a speed-dial code for Redial of two to four characters and the leading or ending character is an asterisk (*) or a number sign (#), the phone user is not required to dial the FSD prefix before dialing the speed-dial code for Redial.

For configuration information, see the "Enabling and Changing Feature Speed-Dial Codes" section.

Enhanced Speed Dial on SCCP Analog Phones

To access predefined speed-dial numbers used with the SCCP telephony control (STC) application, analog phone users must dial a feature speed dial (FSD) consisting of a prefix and speed-dial code, for example *9. The FSD prefix and speed-dial codes are set on the Cisco voice gateway; the telephone numbers that are speed dialed must be configured on your Cisco call-control system.

The speed-dial codes on the Cisco voice gateway are mapped to speed-dial positions on the call-control device, starting with position 1. For example, if you configure speed-dial codes 00 to 20 on the Cisco voice gateway, the system maps code 00 to speed-dial 1 on the call-control device, code 01 to speed-dial 2, code 02 to speed-dial 3, and so on. Dialing 00 on the analog phone dials the telephone number associated with speed-dial 1.

Prior to Cisco IOS Release 12.4(6)T, speed-dial codes for FSDs were limited to a single digit, 0 to 9. In Cisco IOS Release 12.4(6)T and later releases, you can define two-digit speed-dial codes to access up to 99 local speed-dial numbers configured on the call-control device.

Flexible feature access codes (FACs) supports only the feature speed dial (FSD) for Redial. In Cisco IOS Release 12.4(20)YA and later releases, if you configure a speed-dial code for Redial of two to four characters that can be dialed on a phone keypad and the leading or ending character is an asterisk (*) or a number sign (#), the phone user is not required to dial the FSD prefix before dialing the speed-dial code for Redial. For information about Flexible FACs, see the "Flexible Feature Access Codes" section.

To enable FSDs on an analog FXS port, see the "Enabling and Changing Feature Speed-Dial Codes" section.

To use bulk speed-dial codes up to 9,999, no specific configuration is required on the Cisco voice gateway. Analog phone users do not need to use an FSD prefix or speed-dial codes to access bulk speed-dial numbers. See the documentation for your Cisco call-control system for information about configuring up to 9,999 speed dials.

SCCP Meet-Me Conference

In Cisco IOS Release 12.4(20)YA and later releases, hardware-based meet-me conferencing is supported on analog phones connected to the FXS port of Cisco voice gateways. Hardware-based conferencing uses digital signal processors (DSPs) to allow more parties than the three-party limit allowed by software-based ad hoc conferencing. 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 if 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.

In Figure 3, extensions 1215, 1225, and 1235 are all parties in a meet-me conference on extension number 1500. The conference is created as follows:

1. 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.

2. Extension 1225 and extension 1235 joins the meet-me conference by dialing 1500.

3. Extension 1235 joins the meet-me conference by dialing 1500.

Figure 3 Simple Meet-Me Conference

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 signal.

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.

For configuration information, see the "Configuring Feature Access Codes" section.

 pickup different group *#4

 pickup direct *#6

Cisco IOS Release 12.4(20)YA and Later Releases

In the following example configuration, phones users are not required to dial the FAC prefix to access the Call Forward All and Call Forward Cancel features because the feature code is at least two characters and begins or ends with an asterisk (*) or number sign (#), making it a flexible FAC. A phone user must dial only #74 and, following the confirmation tone, the target number to forward all incoming calls to the target phone number.

Router# show running-config

.

.

.

stcapp feature access-code

call forward all #74

call forward cancel 18#

The following output from the show stcapp feature codes command displays the default and nondefault settings for FACs. In this configuration, all of the FACs settings are for default values.

Enabling and Changing Feature Speed-Dial Codes

To enable feature speed-dials (FSDs), define a prefix other than the default (*), and define speed-dial codes, perform the following steps on the Cisco voice gateway.

---

Note This procedure enables analog phone users to access up to 99 speed-dial numbers configured on the call-control device. To use bulk speed-dial numbers up to 9,999, no specific configuration is required on the Cisco voice gateway. See the documentation provided for your call-control system for information on configuring up to 9,999 speed dials.

---

Prerequisites

•Speed dial codes from 0 to 9 require Cisco IOS Release 12.4(2)T or a later release; speed dial codes from 10 to 99 require Cisco IOS Release 12.4(6)T or a later release.

•To use speed-dial codes 34 to 99 on analog phones controlled by Cisco Unified CME, you must configure directory entries in telephony-service configuration mode. The following example sets a directory entry for speed-dial codes 34 and 35. When an analog phone user dials 34, extension 1602 is dialed.

Router(config)# telephony-service

Router(config-telephony)# directory entry 34 1602 name payroll

Router(config-telephony)# directory entry 35 1603 name security

For more information, see "Configuring Speed Dial" in the Cisco Unified Communications Manager Express System Administration Guide.

•To configure an FSD for Redial that does not require the phone user to dial a prefix, Cisco IOS Release 12.4(20)YA or a later release.

Restrictions

•In Cisco IOS Release 12.4(20)YA and later releases, if you configure the same value for more than one feature code or speed-dial code, or for the Redial FSD, the system implements the first feature it matches in the order of precedence shown in the output of the show stcapp feature codes command.

•In Cisco IOS Release 12.4(20)YA and later releases, if you configure feature codes for FACs or speed-dial codes for FSDs, including the Redial FSD, to a value that precludes or is precluded by another code, the system implements the feature with the shortest feature code first. The precluded codes cannot be implemented.
