Most Indian offices bought an EPABX years ago and have kept it because replacing it never reached the top of the list. This page compares the two on the things that actually change your month, and says plainly where an EPABX is still the better answer.
An EPABX is a box in your office that connects phone lines to extensions. A cloud IVR does the same job from the provider’s servers, with your staff’s existing phones as the extensions.
The functional difference is smaller than vendors claim. The operational difference is large: who maintains it, how fast you can change it, and what happens when a staff member works from outside the office.
If your team sits at fixed desks and never changes, an EPABX works. If people move, work from site, or you want to change the menu without calling anyone, cloud wins.
| Cloud IVR | Traditional EPABX | |
|---|---|---|
| Upfront cost | Low. A setup fee at most | Hardware, wiring and installation |
| Monthly cost | A predictable subscription | Lower, until something needs repair |
| Setup time | Usually live the same day | Technician visit and installation |
| Changing the greeting or menu | You do it from a dashboard, free | Vendor visit, usually chargeable |
| Adding a staff member | A setting change | A new extension, sometimes new wiring |
| Staff working outside the office | Calls reach their mobile anywhere | Tied to office extensions |
| Call recording | Built in and searchable | Limited, often a paid add-on |
| Reports | Live dashboard, per-agent data | Basic call logs at best |
| CRM integration | Standard | Rare and expensive |
| If you shift office | Nothing to do | Re-installation cost |
| Who maintains it | The provider | You, or an AMC |
The purchase price is the part everyone compares. These are the parts that show up later.
We would rather say this than pretend otherwise.
If none of these describe you, the question is usually not whether to move, but when.
This is the most common confusion, so it is worth separating clearly.
These are telephony lines and hardware for a full contact-centre operation. They are not part of Cloud IVR. At Sukam Apps they sit under Sukam CallEngine, our call centre solution for teams running large inbound and outbound calling with dialers and AI calling agents alongside human agents.
A cloud IVR works without any of that. You do not need to buy lines, a gateway or a box to run a professional business phone menu.
For most businesses today, yes, because changes are free and instant, staff outside the office are covered, and you get recordings and reports. An EPABX is still reasonable for a fixed office with desk phones, unreliable internet or specific site requirements.
Yes, and that is how most migrations work. Run both in parallel, publish the new business number for customer calls, and keep the EPABX for internal extensions until you decide otherwise.
Your staff receive calls on normal phone calls, so they do not need internet to answer. You need internet to manage the dashboard, view reports and listen to recordings.
Over a typical three-year period it usually works out lower, once you count installation, maintenance, vendor visits for every change, and re-installation if you shift office. The EPABX only looks cheaper in month one.
No. SIP, PRI, VoIP and GSM gateways belong to a full contact-centre setup, which at Sukam Apps is part of Sukam CallEngine. Cloud IVR needs none of that hardware.
Most businesses are live on cloud IVR the same day. The parallel-running period is for your comfort, not a technical requirement.
Keep your EPABX, publish a cloud number alongside it, and compare for yourself. Set up by our team in person across Punjab, Chandigarh, Haryana, Delhi NCR and Himachal.
