An IPPBX (Internet Protocol Private Branch Exchange) is your office telephone exchange running on your computer network instead of separate telephone wiring. Every desk phone, mobile app and branch office connects through the same LAN and internet you already have.
Traditional phone systems send voice over dedicated copper pairs. An IPPBX converts voice into data packets and moves them over Ethernet and the internet. A small server (on-premise box or cloud instance) acts as the brain: it registers your phones, connects calls, plays IVR menus, records conversations and generates reports.
The gap has become enormous. A modern system like Sipon IPPBX adds AI on top of telephony:
Any organisation that handles more than a handful of calls daily: corporate offices, hotels, hospitals, schools, factories, housing societies, government departments and call centers. If your team misses calls, cannot see call reports, or pays for separate phone lines at every branch, an IPPBX pays for itself quickly.
Both are valid. On-premise gives you full data control - the server sits in your office, which many government and enterprise customers in India prefer. Cloud removes hardware maintenance and lets you start small. A good vendor offers both and lets you migrate later.
Entry-level IPPBX systems for small offices start around Rs 15,000. Mid-size deployments with IVR, recording and 50-100 users typically fall in the Rs 1-5 lakh range. Large multi-branch or call-center deployments scale up from there. Monthly running costs usually DROP after migration because SIP trunk call rates are lower and inter-branch calls become free.
