What our customers are saying


At A Glance: FreeSWITCH

Communication is a vital part of the business world. The Internet has provided a wide and varied toolkit for communication through the development of various multimedia technologies, such as voice over Internet protocols, online chatting, and video chatting. These technologies can be combined with traditional telephony to create fully functional communication systems to fit the needs of any size of company. FreeSWITCH is open-source software designed to allow the interconnection of various communication protocols, providing a scalable, multi-platform communication solution for any communication needs. A FreeSWITCH specialist can help you optimize the FreeSWITCH software for your business or project.

A FreeSWITCH specialist is a communications professional with experience in a variety of telephone protocols, voice messaging services, text, and other media formats. A FreeSWITCH specialist can be leveraged as a consultant, helping you identify the needs of your business, developing suggestions and communication solutions, or being relied on to manage and optimize your communication network independently. FreeSWITCH specialists can also embed FreeSWITCH features into websites or webpages, as well as have the software operate as a standalone application. Working with a specialist is an effective way to manage and organize all the different communication components of your business, and since FreeSWITCH is open source, a skilled expert can collaborate with you to implement a highly customized solution for you or your business. Hiring a freelance specialist on Upwork reduces and simplifies the way you and your business communicate.
