Configuring Analog Voice Users

Version 2


    When using an AOS voice product to deliver analog lines to a PBX, key system, or directly to analog phones, voice users must be configured. Below is a sample configuration:



    voice user 1000

    connect fxs 0/1


    voice user 1001

    connect fxs 0/2



    Each voice user is identified by an extension number. This extension can be any number of digits in length and will be used by the internal switchboard for routing decisions.   For more details about the switchboard, document 61210916L1-29.2 - Switchboard and Dial Plan.


    Basic Configuration Steps

    1. Define a voice user using the global configuration command:

    (config)# voice user <NUMBER>


    2. Associate a physical FXS port with the voice user using the voice user configuration command:

    (config-1000)# connect fxs <slot/port>


    Additional Commonly-used Configuration Options

    1. Define a first and/or last name to be used in the display name of the outgoing INVITE:

    (config-1000)# first-name <WORD>

    (config-1000)# last-name <WORD>


    2. Configure a caller-ID override to present in the From user of the outgoing INVITE:

    (config-1000)# caller-id-override external-number <NUMBER>


    3. If the line will be used for fax or modem calls, enable:

    (config-1000)# modem-passthrough


    Note: This is only a few of the many available commands on the voice user. For a more thorough list, please see the ‘Voice User Account Command Set’ in the AOS Command Reference Guide.
