CALLR gives your brand a voice

Here at CALLR, we are excited about the impact that the proliferation of mobile, consumer applications, next-generation hardware, and telecommunications is making on local and international businesses.

We believe that voice technology will be the most critical business driver in the future. We offer custom design software to fit your need and aim to combine voice applications with other innovative technologies in the simplest way possible and put these into the hands of every business, no matter what size.

We help businesses connect, engage and interact with their customers. We provide the building blocks you need to design a smart voice communication infrastructure for your business. Thousands of companies streamlined their comms operations using our API, SIP trunking, and IAX services.

OUR VALUES

We uphold three fundamental values:

  • Simplicity: The world of telco can be cryptic for an outsider: we act as an interface to minimize the telco knowledge you need to interact with the network.

 

  • Sophistication: How to navigate all the features available and make the most of it? We’re here to help you with best practices and tips.

 

  • Cost-Effectiveness: Your business needs solutions that are both cost-effective and easily scalable. CALLR gets rid of unnecessary intermediaries and lets you design a self-sovereign telecom infrastructure: the only one that will scale from your first user to a million.

OUR VISION

We deliver a cutting-edge, enterprise-class platform that brings voice technology to every business communication, relationship, and tool. We are convinced that open source software is the way forward: CALLR is built with FOSS (Free Open Source Software), and we are sharing back our finding and tools with the community whenever possible.

CALLR’s growth is driven by incredible and passionate professionals, starting with its co-founders Taoufik Zagdoud and Florent Chauveau who knew more than nine years ago that voice communications would play an ever-growing role in business relations and sales. The dynamic growth of their company, along with the whole industry proved them right.

OUR MISSION

WE STRIVE TO TAKE THE BEST OF TELECOMMUNICATIONS, MARKETING, AND SALES TOGETHER IN ORDER TO BRING THE POWER OF VOICE COMMUNICATIONS TO EVERY BUSINESS TOOL.
