Cisco IOS Voice, Video, and Fax Configuration Guide

Fine-Tuning Analog and Digital Voice Ports

Normally, default parameter values for voice ports are sufficient for most networks. Depending on the

specifics of your particular network, however, you may need to adjust certain parameters that are

configured on voice ports. Collectively, these commands are referred to as voice port tuning commands.

Note The commands, keywords, and arguments that you are able to use may differ slightly from those

presented here, based on your platform, Cisco IOS release, and configuration. When in doubt, use

Cisco IOS command help (command ?) to determine the syntax choices that are available.

Step 6

Router(config-voiceport)# ring number

number

(FXO only) Specifies the maximum number of

rings to be detected before an incoming call is

answered by the router.

The default is 1.

Step 7

Router(config-voiceport)# ring cadence {[pattern01 |

pattern02 | pattern03 | pattern04 | pattern05 |

pattern06 | pattern07 | pattern08 | pattern09 |

pattern10 | pattern11 | pattern12] [define

pulse

interval

]}

(FXS only) Specifies an existing pattern for ring,

or defines a new one. Each pattern specifies a

ring-pulse time and a ring-interval time. The

keywords and arguments are as follows:

• pattern01 through pattern12—Specifies

preset ring cadence patterns. Enter ring

cadence ? to see ring pattern explanations.

• define pulse interval—Specifies a

user-defined pattern as follows:

–

pulse is a number (1 or 2 digits from 1 to

50) specifying ring pulse (on) time in

hundreds of milliseconds.

–

interval is a number (1 or 2 digits from 1

to 50) specifying ring interval (off) time

in hundreds of milliseconds.

The default is the pattern specified by the

configured cptone locale command.

Step 8

Router(config-voiceport)# description

string

Attaches a text string to the configuration that

describes the connection for this voice port. This

description appears in various displays and is

useful for tracking the purpose or use of the voice

port. The string argument is a character string

from 1 to 255 characters in length.

The default is that no description is attached to the

configuration.

Step 9

Router(config-voiceport)# no shutdown

Activates the voice port.
