EPABX vs. VoIP PBX: Which is the Right PBX for Your Business?
Communication is essential to any organization’s success in today’s
fast-paced corporate world. For communication with customers,
partners, and employees, a dependable and effective phone
system is crucial. Businesses have long relied on Private Branch
Exchange (PBX) systems to manage their phone lines. However,
as VoIP solutions and technology developed, the PBX changed,
with more recent VoIP-based systems taking the place of more
antiquated copper wire-based ones.
Business phone systems come in two different varieties: EPABX and
VoIP PBX or IP PBX. While IPPBX employs VoIP, EPABX requires
copper cables. In order to assist you in selecting which system is
best for your organization, let’s compare the two systems. Systems
like EPABX are more established and have been around for longer.
Despite having greater functionality than IP PBX systems or VoIP
PBX systems, they are often more expensive. Modern IP PBX
systems employ VoIP technologies. They are more scalable and
often less expensive than EPABX systems.

Private Branch Exchanges (PBXs) such as EPABXs (Electronic
Private Automatic Branch Exchanges) link internal phone lines
within an organization and route incoming and outgoing calls. In
particular small- to medium-sized enterprises, EPABX systems are
still employed today as they were in the past.
For the transfer of voice signals between phones and the PBX
system, EPABX uses copper lines. The system then directs the calls
to the appropriate individual within the organization. To enable
the business to place and receive calls from outside, EPABX
systems can be linked to the Public Switched Telephone Network
(PSTN).
A variety of functions, including call forwarding, conference
calling, and voicemail, can be included with EPABX systems. The
extensive functionality and scalability of EPABX systems are
constrained when compared to more recent VoIP-based PBX
systems. Due to the constraints of the copper wire network, it may
be challenging to expand as a business expands, and it can also
result in lower call quality.

An IP PBX system, also referred to as a VoIP PBX system, does not
use analog phone lines to link phones within an organization.
Instead, it transmits voice and data through a company’s network
using internet protocol (IP). IP PBX systems, as opposed to
conventional copper wire-based PBX systems, use the internet to
link phones and route calls, offering a more effective and
affordable communication option.
It can be accessed using a graphical interface or dashboard and
runs through the Internet, making it easier for administrators to
maintain. Furthermore, an IP PBX system’s application
programming interface (API) enables it to be integrated with other
crucial software and apps that an organization may utilize.
As the organization scales up its business, IP PBX systems are easily
expandable to provide high scalability. Additionally, they provide a
vast array of sophisticated capabilities, like voicemail to email
transcription, conference calling, and call routing. Desktop phones,
softphones, and other devices can all be utilized with IP PBX
systems.

What’s IP PBX or VoIP PBX?

5. 5
Tech Aspect
IPPBX systems use internet protocol (IP) technology
to transport voice and data through an
organization’s network, unlike EPABX systems, which
use copper wire technology to transmit voice signals
between phones and the EPABX system. Although
EPABX systems have been around for a while and are
widely established, their technology isn’t very
advanced or scalable. IPPBX systems, in comparison,
are more recent and provide more sophisticated
capabilities, scalability, and flexibility.

Scalability
When a business has to scale up or expand,
EPABX systems often require the addition of new
physical gear and infrastructure. In contrast, as
IP PBX systems are software-based and readily
scaled up or down, they are more adaptable and
ultimately less expensive. The ability to easily
add new lines and services is a key component
of the scalability of IP PBX systems, which is
made possible by VoIP solutions.

Advanced capabilities
Although both EPABX and IP PBX systems
provide essential functions like call forwarding
and voicemail, IP PBX systems provide a
greater range of advanced functionality. Auto-
attendant, call routing, and voicemail-to-email
transcription are a few of them. VoIP
solutions make it possible to add
innovative capabilities, enhancing the
productivity and effectiveness of IP PBX
systems for contemporary businesses.

Cost
As EPABX systems rely on solidified copper
wire technology, they can be less expensive
upfront. However, over time, the price of
upkeep and improvements may rise. However,
IP PBX systems may cost more upfront, and
their scalability and flexibility result in long-
term cost benefits. Since it requires less
physical equipment and infrastructure, VoIP
solutions significantly contribute to cost
savings for IP PBX systems.

Reliability
Since EPABX systems have been in use for a
long time and are successful, it is a
dependable solution. However, because of
their dependency on physical infrastructure,
they may experience downtime and poor call
quality. On the other hand, IP PBX systems are
more dependable since they make use of
more resilient and adaptable internet protocol
technology. Due to their ability to provide
redundancy and backup options, VoIP
solutions increase the resilience of IP PBX
systems.

Security
Due to their reliance on physical infrastructure
that may be subject to hacking and other
security risks, EPABX systems are typically
thought to be less safe than IP PBX systems.
Encryption and other security measures are used
by IP PBX systems to thwart hackers. Since VoIP
solutions provide encryption and other security
measures for voice and data transfer, they
significantly contribute to the security of IP PBX
systems.

The Bottom Line for EPABX and IP PBX
In a nutshell, EPABX and IPPBX systems each have specific benefits
and drawbacks. While IPPBX systems provide scalability and cutting-
edge features, EPABX systems are dependable and well-known.
However, IPPBX systems that utilize VoIP solutions are now the
favored option for many businesses due to the rising demand for
flexible and effective communication solutions.
