VOIP Solution
Design and manage business voice communication systems

At Zeron Technologies, we design and implement Voice over Internet Protocol (VoIP) communication systems using an Asterisk-based FreePBX server. Our VoIP solutions enable voice communication over an IP network, replacing traditional PSTN-based telephony with a cost-effective, scalable, and flexible solution that modernizes your business communications.
Our VoIP system supports internal and external calling, user extensions, call routing, voicemail, and other essential PBX features. We use FreePBX as a graphical interface to manage and configure the Asterisk server efficiently, making it easy for your team to maintain and customize the system.
