# auphone(1nas)

a simple telephone client

## NAME

auphone - a simple telephone client

## SYNOPSIS

**auphone** \[**-a** *servername*\] \[**-v** *volume*\] \[**-l** *latency*\] \[**-r** *filename*\]

## DESCRIPTION

*auphone* allows two-way real time voice communication between two audio servers.

## OPTIONS

The following options can be used with *auphone*:

- **-a** *servername*

  This option specifies the audio server to which *auphone* should connect.

- **-v** *volume*

  This is the volume, in percent, for the incoming ring sound.  The default is 15 percent.

- **-l** *latency*

  This is the latency, in seconds, of the auphone connection.  A lower value will result in better real-time communications at the expense of possibly overloading the server (causing dropouts) and a greater network duty cycle.  A higher value will lessen the load on the server and decrease the network duty cycle but will increase the communications delay.  The default value is .25 seconds.

- **-r** *filename*

  You can personalize your incoming ringing sound using the *-r* option.  Simply specify the filename of an audio file to use for the incoming ring sound.  Note that this sound will be looped.

## USAGE

To place a call, enter the address of the audio server that you wish to connect with in the *Who* text field.  Then hit RETURN or click on the **Call** button.  If the callee is accepting calls, you should hear a ringing sound.  If the callee answers, the username and server address of the callee will be displayed.  To disconnect, click on the **Hangup** button.

To receive incoming calls, you must already be running *auphone*. To answer an incoming call, click on the **Answer** button.  You may also determine who's calling before you answer by clicking on the **Caller ID** button.

Once you're connected, the **Volume** slider controls the volume of the speaker output and the **Input Gain** slider and **Input** **Mode** toggle control the gain and mode of the microphone or line input.

## AUPHONE AND THE ATHENA WIDGET SET

*auphone* uses the X Toolkit Intrinsics and the Athena Widget Set. For more information, see the Athena Widget Set documentation.

## ENVIRONMENT

In addition to the standard toolkit environment variables, the following environment variables are used by *auphone*:

- **AUDIOSERVER**

  This variable specifies the default audio server to contact if *-a* is not specified on the command line.  If this variable is not set and the *-a* is not specified on the command line, *auphone* will attempt to connect to the audio server running on the X Window System display.
