SimpleDialer

This is alfa version.Simple dialer is a system for automatic dialing of subscribers using an asterisk.

• Used only by AMI
• Simple configuration
• Progressive mode
• Autoinforming mode

In future releases

• Predictive mode
• Webphone
• Realtime statistics and more

Software requirements

Asterisk:

• Asterisk 16.X

Databases that can be used:

• Postegresql 12.X
• MariaDB 10.3.X

Usage

• Install
  • Database
    • Create dialer tables
      • Сolumn description
    • Create dialer cases
• Dialer management

Install

• Create tables in database
• Configure asterisk and dialer configuration files
• Create cases for calling
• Send Get query for start

Dialer management

• A get request is used to control the dialer
• Parameters used: action and projectid where action can be start or stop

Example:http://127.0.0.1:8080/?action=start&projectid=test

Add dialer cases and params(Example)

INSERT INTO nc.dialer_clients (case_name, project_id, phone_number, priority, utc,recall, allowed_start, allowed_stop, recall_period) VALUES('Name', 'test', '1111', 1 , '+03.00h',true, '10:00:00', '18:00:00','1,1' );

INSERT INTO nc.dialer_params (project_id, lines, call_time, case_limit, type, exten, context) VALUES('test', 0, 20000, 500, 'progressive', '2222', 'default');
