Why EPABX is Dying
Transitions in any technology are most visible through the exit of major industry players. Over the last five years, several high-profile EPABX brands have withdrawn from the market — ironically during their peak business period.
In India, a market once dominated by multiple MNC and homegrown EPABX brands now stands with only two significant traditional players — Matrix EPABX and Alcatel EPABX. Meanwhile, IP PBX solutions are witnessing remarkable growth.
See Full ComparisonEPABX Market Shrinking
Major brands have exited despite peak business periods — a clear signal of structural decline in traditional PBX.
Only 2 Players Remain
India's once-crowded EPABX market now has only Matrix and Alcatel as significant traditional players.
IP PBX Rising Fast
Grandstream IP PBX has seen remarkable growth, emerging as the only true IT-focused IP PBX brand with rapidly rising market share.
The Bottom Line
"Replacing legacy EPABX is now cheaper than paying AMC to the old vendor."
Digital EPABX Masquerading as IP PBX
Adding VoIP cards to a PCM/TDM system is NOT an IP PBX. Here is the truth the industry doesn't want you to know.
PCM/TDM = IP PBX
Adding VoIP or bridge cards to a digital EPABX is often presented as IP enablement. Vendors claim this makes their system an IP PBX. Customers believe it — and pay a premium for it.
"This approach is merely a backward integration of already obsolete PCM/TDM technology, masquerading as IP technology."
PCM/TDM Cannot Become Native IP
They can only bridge voice through proprietary, limited modules. Advanced IP-native features — APIs, multimedia, cloud scalability — remain completely unavailable.
- Limited channels & poor scalability
- No API / CRM integration
- Multi-location = complex nightmare
- No cloud or hosted deployment
The Redax Difference
Redax IPPBX is 100% Native IP — Built from the Ground Up
No PCM/TDM heritage. No proprietary bridges. Pure SIP, open hardware, and a software-defined architecture that scales from 100 to 8,000 extensions without compromise.
Request a Live DemoRedax IPPBX vs Digital EPABX
Smart customers now bypass EPABX restrictions by upgrading to open, modern IP systems — often at a cost lower than the support fees quoted by old vendors.
Incompatible across brands and even models. Customers fully dependent on dealer.
Runs on any standard desktop/server hardware. ISO installer online. Reinstall in under an hour.
Dealers charge 1.5–2× more for replacement digital phones.
Open-standard IP phones from any supplier. Add, replace, or expand with full freedom.
Every extension cable routed back to main system. Messy and expensive.
Uses IP network as backbone. Reduces traditional telephony cabling by 60–70%.
Fixed slots. Must replace entire system at extreme cost to expand.
Software-defined. Scale from 100 to 8,000 IP extensions without hardware replacement.
Heavy investment tied to infrastructure. Dealers impose rigid terms.
80%+ open-source components. Replacement: plug out old, plug in new.
Sell at cost, recover profits after warranty. AMC rates are extortionate.
80% open-source parts. Dealers compelled to offer fair AMC throughout system life.
Wait for failure, then overcharge heavily to recover past losses.
Software-driven on universal hardware. Drastically reduces hardware failure risk.
Multiple layered licenses: extensions, SIP trunks, third-party phones, channels.
SIP is native. No additional licenses for extensions, SIP phones, or channels.
Mandatory packs from Alcatel, Avaya. Non-renewal = no support at original system price.
No hidden policies. Software Assurance is nominal, flexible, starts only when you request support.
