From PBX to Advanced VoIP Systems: Sheerbit’s Asterisk Expertise

In the ever-changing digital communication landscape, traditional PBX systems are transitioning to more advanced and scalable VoIP solutions. At the center of this transition is Asterisk, a telecommunications open-source framework that allows businesses to develop telephony systems to take control of their calls. Businesses of any size from small startups to large enterprises now have the option of developing a communication platform that is robust, flexible and customizable.

At Sheerbit, we are an Asterisk development company and a leader in the Asterisk development services area. We offer a wide array of Asterisk development services that range from basic VoIP implementations to complex, multi-tenant PBX systems. In this article, we will explain what our clients needed from their traditional PBX systems to migrate to an advanced VoIP infrastructure, along with the reasons why businesses hire Asterisk developers from us to develop their communication strategies.

The Evolution: PBX to VoIP

Traditional PBX systems have been around for decades and have been the primary method of calendar communication. The problem with PBX systems is that they are expensive hardware, not easily scalable, and upgrades are expensive. VoIP (Voice over Internet Protocol) provides businesses with cheap solutions that communicate through the internet with voice, video, and messaging all encompassed in one area.

In this space, Asterisk was born and developed by Digium and is still maintained today with a community of developers around the world. It is open-source, meaning developers can modify and extend the power of the framework for their purposes instead of a proprietary system.

Because of this, businesses have begun gravitating toward Asterisk VoIP systems because they can be cheaper and more flexible.

Asterisk Is the Core of Today’s VoIP Systems

Asterisk is not just software, it is a whole platform that can create near limitless communication solutions:

Voicemail, IVR, call queues and conferencing
SIP trunking and session control
Integrations in CRMs/ERPs/Custom Applications
Secure, encrypted communications

Whether you need to build a hosted PBX for various end users or have an internal communications system, Asterisk has the power and flexibility for you.
