Preface

This preface discusses the objectives, audience, organization, and conventions of this document. It also provides sources for obtaining documentation from Cisco Systems.

This document is intended primarily for users who configure and maintain Cisco SRS Telephony but who may not be familiar with the tasks, the relationship between tasks, or the Cisco IOS software commands necessary to perform particular tasks. This configuration guide is also intended for those users experienced with Cisco SRS Telephony who need to know about new features, new configuration options, and new software characteristics in the current Cisco IOS software release.

Documentation Organization

This document consists of the following chapters:

•"Cisco SRS Telephony Overview," which includes product history, prerequisites, and reference information.

•"Cisco SRS Telephony Configuration," which includes prerequisites, restrictions, background information about Cisco SRS Telephony, and descriptions of how to perform basic, required configuration, and additional configuration tasks for the following features:

–Unmatched dial-peer routing

–Cisco IP phone date and time display formats

–Phone setting based on MAC addresses

–Keepalive intervals

–Default destinations for incoming calls

–Global prefixes

–Call transfers from Cisco IP phones to other phone numbers

–Trunk access codes

–Message button phone numbers

–Class of restriction (COR) on the dial peers associated with directory numbers

–Call forwarding during a busy signal or no answer

–Translation rules for numbers dialed on Cisco IP phones

–Interdigit timeout value for all Cisco IP phones attached to the router

–Music on hold

–Dial-peer hunting

•"Command Reference"

Documentation Conventions

Within Cisco IOS software documentation, the term router is generally used to refer to a variety of Cisco products (for example, routers, access servers, and switches). Routers, access servers, and other networking devices that support Cisco IOS software are shown interchangeably within examples. These products are used only for illustrative purposes; that is, an example that shows one product does not necessarily indicate that other products are not supported.

The Cisco IOS documentation set uses the following conventions:

Convention

Description

^ or Ctrl

The ^ and Ctrl symbols represent the Control key. For example, the key combination ^D or Ctrl-D means hold down the Control key while you press the D key. Keys are indicated in capital letters but are not case sensitive.

string

A string is a nonquoted set of characters shown in italics. For example, when setting an SNMP community string to public, do not use quotation marks around the string or the string will include the quotation marks.

Command syntax descriptions use the following conventions:

Convention

Description

boldface

Boldface text indicates commands and keywords that you enter literally as shown.

italics

Italic text indicates arguments for which you supply values.

[x]

Square brackets enclose an optional element (keyword or argument).

|

A vertical line indicates a choice within an optional or required set of keywords or arguments.

[x | y]

Square brackets enclosing keywords or arguments separated by a vertical line indicate an optional choice.

{x | y}

Braces enclosing keywords or arguments separated by a vertical line indicate a required choice.

Nested sets of square brackets or braces indicate optional or required choices within optional or required elements. For example:

Convention

Description

[x {y | z}]

Braces and a vertical line within square brackets indicate a required choice within an optional element.

Examples use the following conventions:

Convention

Description

screen

Examples of information displayed on the screen are set in Courier font.

boldface screen

< >

Angle brackets enclose text that is not printed to the screen, such as passwords.

!

An exclamation point at the beginning of a line indicates a comment line. (Exclamation points are also displayed by the Cisco IOS software for certain processes.)

[ ]

Square brackets enclose default responses to system prompts.

The following conventions are used to attract the attention of the reader:

Caution Means reader be careful. In this situation, you might do something that could result in equipment damage or loss of data.

Note Means reader take note. Notes contain helpful suggestions or references to materials not contained in this manual.
