Mute and volume button missing the agent screen.

  Overview: Mute and volume button missing

    In the latest installation of vicidial or vicibox you might be missing the Mute and Volume control button in the agent screen, which is available by default in the previous installation versions.
    The reason behind this is that due to instability of vicidial system with asterisk 13 and later (asterisk 16) the mute and volume control buttons are disabled by default in the latest vicidial vicibox installations.
    In this article i have given the steps to enable the mute and volume control button in the agent screen.

  vicidial / vicibox

    VICIdial is an enterprise class, open source, contact center suite in use by many large call centers around the world. VICIdial has a full featured predictive dialer.  It is capable of inbound, outbound, and blended phone call handling. 
    VICIbox Server is the official installation CD for the VICIDIAL Call Center Suite. It is based off of OpenSuSE server, and will properly install the VICIDIAL Call Center Suite with relative ease.

  Workaround: vicidial mute-volume buttons

    Due the system instability of vicidial with asterisk 13 and asterisk 16 , the Mute and volume button is disabled by default, this particular option can be overridden by enabling the volume control option in options.php located in the agc web directory.

    Note: The options.php also disabled by default by vicidial, but it is placed in the agc web folder in the name of options-example.php.

Agent Panel without Mute and volume controls

Follow the below steps to Enable the Mute and volume control button

Login to Linux console
SSH or login to the vicidial linux console
navigate to the agc web folder path 
for vicibox users the web folder path is /src/www/htdocs/agc
for other scratch it could be /var/www/html
this path may differ according to your Linux flavor and installation method

cd /srv/www/htdocs/agc/

or

cd /var/www/html/agc/

Copy and rename the options-example.php

cp options-example.php options.php

Edit the Options.php
Now you need to edit the options.php and enable the below options

vi options.php

change

$volumecontrol_active   = '0';

to

$volumecontrol_active   = '1';

Change

$ast13_volume_override  = '0';

To

$ast13_volume_override  = '1';

  Conclusion

    As it is mentioned enabling the volume control will cause serious issue in the vicidial system, better enable if you badly required this option, hope this will be rectified in upcoming asterisk and vicidial installations
