What Is Asterisk?

Asterisk is an open-source communication platform that acts as the engine behind many PBX (Private Branch Exchange), VoIP (Voice over IP), and UC (Unified Communications) systems. Developed and maintained by Digium, now part of Sangoma Technologies, it has become a go-to option for call centers seeking both flexibility and control over their telephony environment.

Unlike rigid commercial phone systems, Asterisk is highly customizable, allowing developers to create tailored solutions that match their unique business needs.
