What an EPABX does for your business
An EPABX system helps users manage telephone calls within a business or building. Staff dial each other by extension, calls from outside reach the right desk, and the business keeps its phone service running as it grows. For a front desk, a hotel or a factory with many departments, it is the difference between one rung number and a managed set of lines.
EPABX features
Essatech supplies, installs and services these systems in Hyderabad and Visakhapatnam. The call features buyers use most are:
- Call transfer
- Call pickup
- Backup calls
- Conference calls
What is inside an EPABX system
The unit houses these components together:
- CPU, the control unit that runs the system
- UPS, so calls continue through a power cut
- BC extension cards, which connect the extensions
- LC line card, which connects the outside lines
- Primary digital trunk card, for a high-capacity digital line
Choosing the right size
Two numbers decide the size: the number of extensions inside and the number of lines to the outside. A system that is too small stops you from adding a desk, and one that is too large wastes money. We ask how many people you have today and how many you expect in two or three years, and we choose a system that can grow by adding cards, not by replacing the unit.
Where EPABX systems are used
These systems serve the telephone communication needs of these buildings and workplaces:
- Offices
- Shopping malls
- Hotels
- Industries
- Apartments
What you get from Essatech
We deliver the system as a complete job:
- A free site visit to count extensions and plan the cable
- A recommendation on the system size and the line type
- Supply and installation of the unit, extension wiring and phones
- Programming of extensions, call groups and the answering sequence
- A handover for your reception or admin team
- Maintenance and support afterwards
Cabling and networks
The phones need cable, and the cable is often the larger part of the work. If you are also putting in a computer network, the two can share the same cabling plan, which saves cost. See our LAN, WAN and Wi-Fi solutions for structured cabling, and we can link the system to a public address system for announcements.
Testing and upkeep
A phone system must work every day. At each service visit we check the power backup, test lines and extensions, review the call settings and clean dust from the unit. If a number of extensions go dead, the usual cause is a failed card or a cable fault, which we trace and replace on site. Keeping a spare card for a critical line saves a long outage.
Why buy from Essatech
Essatech has been in business for more than 15 years and works as a turnkey contractor, so the same team can plan your phone system, your network cabling and your security systems. Its licensed team brings 80 years of combined experience, and we aim to keep the total cost of owning the system low.
For builders, architects, MEP consultants, corporates, industries, hospitals and defence
Builders and architects should plan phone cabling with the data network, with riser space and an equipment room. Commercial building owners need extensions per tenant and room to grow, and industries need lines across plants and offices. Hospital owners need reliable internal dialling between wards, pharmacies and departments, with power backup so the system keeps working in a power cut. MEP consultants can send the telephone specification and we price the system and cabling. Corporates need extensions across floors and sites. Defence establishments, including Navy and Army offices and residential blocks, need dependable internal telephony, and we quote within their security and vendor-registration rules.
What decides the cost
A quote depends on:
- The number of extensions and outside lines
- The line type: analog or digital trunk
- The type of phones, from basic to display and IP phones
- Cable length and the power backup
