Software PBX is a software-based phone system that replaces traditional hardware-based PBX systems. It runs over your internet connection using VoIP technology instead of analog phone lines or digital ISDN connections, and can be installed on hardware or virtual servers you already own.
Do I need hardware with Yeastar PBX software?+
Not necessarily. The Yeastar P-Series Software Edition can be self-hosted on your own server — a physical machine, a virtual machine or a cloud server — so you can deploy it on existing hardware or in a cloud environment that best suits your business.
How does software PBX work for a business?+
A software PBX uses VoIP to handle and route calls over the internet, replacing legacy hardware phone systems. It delivers call routing, voicemail, conferencing and more — helping businesses streamline communication, cut costs and scale easily with advanced functionality.
What size of business is Yeastar PBX software suitable for?+
Capable of handling up to 10,000 users and 1,000 concurrent calls, the Yeastar Software Edition suits businesses of all sizes — from small teams to large enterprises — and scales as the business grows. It is available in India through Cohesive Technologies, the authorized Yeastar distributor. Call +91 120 4830000 or email sales@cohesiveglobal.com.
