New Facts About EPABX/Intercom You Didn’t Know


An EPABX/intercom system can serve as the foundation of your company’s internal communications, regardless of how big or small your operation is. Apart from offices, this method can be extremely helpful for residences, schools, universities, hotels, and many other businesses with many divisions and a large workforce.

EPABX/ Intercom System

Discuss EPABX:

  • A private telephone network known as EPABX.
  • EPABX Full Form is “Electronic Private Automatic Branch Exchange,” is used by businesses and organisations for a variety of internal and external communications. 
  • The acronyms PABX and EPABX stand for Private Automatic Branch Exchange and Electronic Private Automatic0020 Branch Exchange, respectively.
  • This method makes it possible to link all the phones within a company or among various places.

How does EPABX function?

  • The EPABX functions just like an exchange, sending, receiving, and forwarding calls from the company to external parties. The PBX is where a number of lines entering the building come to an end. 
  • Additionally, a number of internal building lines also come to an end at the PBX switchboard. Additionally, the external lines could originate from other ISPs and use a totally different form of communication.

  • The external communication channels include satellite, VoIP, GSM/CDMA, and the PSTN. Standard phones are most often used for internal communication. Most of the time, there is no need for an operator at the electronic private branch exchange. 
  • As a result, it reduces the amount of human work required to transfer incoming and outgoing calls. Numerous calls are made at once in large businesses, which rely heavily on communication. Computers eliminate the need for human labour and easily transfer calls.

EPABX/Intercom design and implementation:

  • The PBX Equipment Must Be Programmed.
  • A private telephone exchange that is specifically used by a company or organisation is known as an EPABX system. It is an economical method of facilitating employee communication in an organisational setting. Different EPABX system types are offered on the market since different businesses have various needs.
  • Any EPABX system may only be setup by professionals. But going over the following information will help you become ready for the installation of this system in your office.

EPABX Installation: 

1. Examine the Location

  1. Examine the area where the EPABX Service will be installed before installation. Choose a location with good protection from rain and other natural deterrents. 
  2. It is possible to inspect and choose an area with air conditioning, power backup, a power connection, and earthing.
  3. It is advised that a wiring schematic of the planned connection be created, clearly identifying all of the modules, including the PBX machine, computer for programming and monitoring, battery connection, etc.

2. Extension line wiring:

  1. After the wiring plan and connection configuration are complete, wiring for the extension lines must be completed. 
  2. Redundancy and future improvements must be considered, and the appropriate preparations must be made. 
  3. Choose sealed wiring whenever possible since open wiring increases the risk of cable cutting and disconnecting.

3. Setting up the PBX system:

  1. The wiring must be finished before configuring the EPABX device. 
  2. The necessary features must be properly wired and documented, including the number plan, a list of extension lines, etc. 
  3. For future use, extension numbers must be kept on the MDF (Main Distribution Frame). 
  4. The machines must be carefully sealed after being numbered and tagged to prevent unauthorised individuals from making any alterations.
  5. The wiring can become fairly complicated in a large firm with a complicated PBX system, and the details are quite minute. 
  6. Additionally, it requires greater planning and documentation. 

g. Make sure to only use authorised professionals to install the    EPABX system in your office. (For more Details…)

Pros of EPABX/Intercom System:

Let’s explain its 5 advantages in more detail below:

  • Intracompany communications
  • Controlled Centrally
  • Automation 
  • Modular Call Routing
  • Modular Access

You might not know that when you place a call in your office, the call is first forwarded to the local phone company’s exchange before it is connected to the person you are trying to reach. There can be a fee for using this connection type. An EPABX system will therefore route calls within rather than outside the premises.

2. Controlled Centrally:

  • It is not required to give each new contact a list of numbers for future interactions, even though PBX permits a list of numbers to be placed within its system. 
  • If it had been that way, the PBX system would have already lost favor due to its intrinsic complexity. The receiving component of the EPABX system, however, provides a simpler fix.
  • When a guest enters an office, the receptionist is usually the first person the visitor encounters. The visitor and the office are connected through this initial engagement. 
  • Similar to this, the EPABX has a function that enables all incoming calls to arrive at a single receiving point with a single number before being routed to the appropriate departments. 
  • This makes it possible to reach several contacts using just one number. As a result, having an EPABX intercom system installed in any office makes keeping business contacts simpler and more seamless.

3. Automation:

You do not need to hire a person to answer calls with this phone system, which is one of its advantages. It provides “auto attendant” instructions for your business. This further instructs you to call a specific number to access a particular service.

4. Modular Call Routing:

Another function that sets PBX devices apart from conventional phones is the call routing capability. You can design the PBX phone to route the call to the number where you will be available if you are anticipating a specific call at a specific time of day but you unexpectedly had to attend an emergency meeting in a different place. Therefore, regardless of where in your office you are, there is no possibility that you will miss any of your crucial calls.

5. Modular Access:

The likelihood of excessive phone use increases when a person’s phone is still within reach. Each phone connected to the EPABX system has a distinct extension, which can also be monitored. The services can be restricted to only provide incoming facilities for those chosen extensions if you do not want part of them to have outgoing amenities from the desks.

Long-distance and international calls are subject to comparable restrictions. If you anticipate any potential of misuse, you might restrict the services for the remainder while keeping a few extensions allotted to the top management personnel. Consequently, the EWPABX intercom system is efficient at managing the communications in an intelligent manner.

Cons of EPABX/Intercom System:

Let’s explain its 5 advantages in more detail below:

  • Customer service has a disability
  • Continuous power supply
  • A nomadic worker is not provided with communication connectivity
  • The standard system requires significant investment to install and    configure
  • Downtime for upgrades and maintenance

1. Customer service has a disability:

  • The installation of new features takes a long time, and it lacks other essential functionality.

2. Continuous power supply:

  • It calls for careful infrastructure planning and design to reduce power usage as well as careful cabling to prevent power outages caused by faulty wiring.

3. A nomadic worker is not provided with communication connectivity:

  • This restricts the capacity of companies with a sizable number of travelling workers.
  • Upgrading to this system with installed integrated gateways is one method to fix this.

    4. The standard system requires significant investment to install and          configure:

  • It costs a lot of time and money to initially set up and configure the devices. This can be reduced by utilising virtual programmes or by setting up an effective network without extraneous hardware.

5. Downtime for upgrades and maintenance:

  • The system is shut down during this period, costing a business a great deal of money.
  • Implementing updates would be a remedy for this.
  • A backup server or system might potentially be set up to prevent downtime, but this would require a significant investment in additional hardware. 

Guidance of EPABX/Intercom:

Using Intercom Phone for Office, these are the Guidance;
