About CCL EPABX System
What is CCL EPABX?
CCL (Computer Consoles Limited) is one of India’s leading manufacturers of EPABX, IP PBX, Intercom, and Unified Communication systems. CCL provides reliable and scalable business communication solutions for organizations of all sizes. Its systems are widely used in offices, hotels, hospitals, schools, factories, banks, and government institutions.
History of CCL:
CCL was established in 1983 and has over four decades of experience in the telecommunications industry. The company designs and manufactures communication products in India, focusing on innovative, high-quality, and cost-effective telephone systems for business communication.
Features of CCL EPABX:
CCL EPABX systems provide a wide range of features, including extension dialing, call transfer, call hold, call forwarding, conference calling, caller ID, auto attendant (IVR), voicemail, music on hold, DISA, call recording, and remote extension support. Many models also support SIP trunks and IP telephony, making them suitable for modern communication networks.
Smooth Call Transferring and Forwarding:
This feature allows a call to be transferred or forwarded to the appropriate person or department without disconnecting the caller. It helps businesses route calls quickly and ensures customers reach the right employee. For example, if a customer calls the reception and asks for the Accounts Department, the receptionist can transfer the call directly to the Accounts extension.
Automatic Redialing:
Automatic Redialing enables the telephone to automatically redial a busy or unanswered number. This saves time and eliminates the need to dial the same number repeatedly. For example, if you call your manager and the extension is busy, the phone will continue trying until the line becomes available.
Auto Conferencing:
Auto Conferencing allows three or more people to participate in the same telephone conversation. This feature is useful for meetings, technical support, and discussions involving multiple departments. For example, a Sales Executive can add a Technical Engineer to the call while speaking with a customer.
Call Waiting:
Call Waiting notifies you when another call arrives while you are already on a call. The phone usually gives a beep tone or flashes an indicator light. For example, while speaking with one customer, you hear a beep indicating another customer is calling your extension.
Call Hold:
Call Hold allows you to temporarily place the current caller on hold while you check information or answer another call. The caller remains connected and usually hears music or an announcement. For example, you place a customer on hold while confirming product availability with the warehouse.
Call Park:
Call Park allows a call to be placed on hold and retrieved from a different extension. This feature is useful when the person who needs to answer the call is in another office or department. For example, the receptionist parks a call, and the manager retrieves it from another extension.
Call Hunt:
Call Hunt automatically forwards an incoming call to another available extension if the first extension is busy or does not answer. This helps reduce missed calls and improves customer service. For example, if Sales Extension 201 is busy, the system automatically rings Extension 202.
Music on Hold:
Music on Hold plays music or a recorded message to callers while they are waiting. This keeps callers engaged and provides a professional experience instead of silence. For example, a customer hears background music while waiting for the support team to return to the call.
Make Set Busy:
Make Set Busy temporarily prevents the telephone from ringing during meetings or when the user is unavailable. Incoming callers receive a busy tone or are redirected according to the system settings. For example, a manager activates this feature before attending an important meeting.
Message Waiting Indicator:
The Message Waiting Indicator informs users that a new voicemail has been received. Most telephones display a blinking light or message on the screen until the voicemail is checked. For example, after returning from lunch, an employee notices the message light blinking and listens to the customer’s voicemail.
Last Number Redial:
Last Number Redial allows the telephone to automatically dial the most recently called number without entering it again. This is useful when a call is disconnected or the number is busy. For example, if a supplier’s call drops unexpectedly, pressing the Redial button immediately reconnects the call.
Applications of CCL EPABX:
CCL communication systems are widely used in offices, hotels, hospitals, educational institutions, factories, banks, shopping malls, government organizations, and call centers. They improve internal communication, simplify call management, and enhance customer service.
Conclusion
CCL EPABX is a dependable and feature-rich business communication system designed for organizations of all sizes.
