Newfies is an open source VoIP Dialer and SMS broadcasting system based on distributed message passing. It has been built to support cloud based servers and can also work on standalone servers. It uses Freeswitch (VoIP Server) to outbound calls.

The platform is focused on real-time operations and task call distributions to clustered brokers and workers.

Newfies-Dialer is written in Python, using the Django Framework. It also operates with message brokers such as RabbitMQ, Redis but support for Beanstalk, MongoDB, CouchDB and DBMS is also available.

Newfies-Dialer provides an extensive set of APIs to easily integrate with third-party applications. Virtually every feature on the UI can be managed via the API’s. There is also an API explorer to test different features.

Using very simple steps, Newfies-Dialer will help you create campaigns, add phonebooks, contacts, build audio messages and create complex telephony applications. Once the campaigns are ready to start, the messages will be dispatched and delivered.

Overview

Newfies-Dialer can be installed and used by anyone who has a need for SMS broadcasting, mass outbound calling, voice broadcasting or providing outbound IVR Some of the potential uses for Newfies-Dialer are listed below.

The system may be installed and used by either companies who wish to make calls on their own behalf, or by SaaS (Software as a Service) companies that want to provide bulk dialling and SMS broadcasting facilities to their own customers.

Newfies-Dialer can be configured on a single server, or for really high capacity or high speed systems, Newfies-Dialer can be configured across multiple servers.

Utility

Newfies-Dialer is loaded up with a list of telephone numbers that can be dialled sequentially at very high rates of calling depending on carrier capacity and hardware, potentially delivering many millions of calls per day.

When the called party answers the call, Newfies-Dialer passes the call to a telephony application that is custom designed to provide the desired behaviour.

Some examples of where Newfies-Dialer may be used follow:

• Telecasting: Broadcast marketing or informational messages to customers and clients.
• Phone Polling, Surveys and Voting: Ring large numbers of people and present IVR options for either polling their opinions, interactive surveys, or taking their vote and record the results.
• Debt Control: Customers can be automatically reminded at intervals that they owe money, and an IVR menu presented to talk to the finance department or passed to a credit card capture IVR to pay over the phone.
• Appointment Reminders: Doctors, Dentists, and other organisations that make appointments for their clients can integrate Newfies-Dialer into their appointment systems to pass a message reminding clients of an upcoming appointment.
• Dissemination of information via phone: Newfies-Dialer was originally designed to call large numbers of people and disseminate medical and health advice via cellphone in 3rd world countries where often, literacy levels are low. On a local scale, it can be used to disseminate information about forthcoming community events.
• Mass Emergency broadcast: Where there is a necessity to warn large numbers of people in a short space of time, such as weather warnings, evacuation notices and crime prevention.
• Subscription Reminders and Renewals: Where a company sells an annual subscription for a product or service, Newfies-Dialer can be configured to dial the customer, remind them that the subscription is due.

Architecture

• User selects contacts, phonebooks and campaigns, then chooses a voice application to use. The campaign is then launched
• Newfies-Dialer spools the outbound calls to FreeSWITCH via ESL.
• FreeSWITCH dials the contact via the configured telephony gateways.
• Contact picks up the call, and the answer event is received in FreeSWITCH and passed back to the Lua IVR Application.
• Newfies-Dialer is notified that the call is answered, then renders the appropriate IVR.
• The application is delivered to the contact by FreeSWITCH.
