Getting Started with GranSun VOIP

We are a business-focused Voice over IP (VoIP) service provider. The purpose of this wiki is to support our clients, customers, and partners by providing easy access to information about our products and services.

What is GranSun VOIP

GranSun utilizes a Private Branch Exchange (PBX) system, which enables extension phones within one office to connect with the telephone network in other locations. This setup allows organizations to efficiently manage incoming and outgoing calls, as well as internal communications. Additionally, GranSun employs Session Initiation Protocol (SIP) to replace traditional analog phone lines, linking the PBX system to the internet for seamless VoIP connectivity.
