Key features of phone systems for large businesses
Large-scale enterprises require a PBX phone system capable of streamlining a web of company-wide communications.
To optimise internal communications and client communications, implementing an analogue, hybrid or cloud PBX phone system that supports a range of features is important.
We provide business telephone systems that include many basic and high-end features designed to increase productivity and efficiency.
Let’s dive deeper into these key features.
Real-time call monitoring enables supervisors to listen in on calls, subtly advise employees on calls, or join a call undetected by other participants, thereby enhancing service quality and staff performance. A powerful training instrument.
Auto-attendant, offers an automated menu of pre-recorded options to help direct calls to the right department without requiring a human operator. This feature enhances your business’s call-handling process and overall efficiency.
Four standard voicemail licences come with many of our business phone systems, with the flexibility to add more as required. Users can customise the voicemail message for callers and get alerts for new messages, thereby boosting efficiency and elevating the quality of customer service.
Fixed Mobile Convergence (FMC) creates a unified solution for smartphones and other company devices enabling users to place and receive calls through a centralised PABX system. By installing a softphone extension on each device, a user can be integrated as an extension of the organisation’s PBX system.
A telephone management system is a third-party software linked to your office phone system, monitoring key metrics (including call volume and duration) across extensions. This system can provide reports to analyse trends and identify opportunities
The term Unified Communications (UC) signifies a consolidated communication infrastructure within an organisation. United Telecoms helps clients in tailoring a UC solution for their organisation, providing benefits like centralised communications and management, lower costs, enhanced productivity, customer service and much more.
Music on hold provides businesses with the ability to tell their unique story while customers are waiting for support. At United Telecoms, we work closely with clients and professional voice-over agencies to create engaging music-on-hold scripts. This flexible marketing tool, great for businesses of any size.
VoIP (Voice over Internet Protocol) has revolutionised the telecommunications landscape relying on your internet connection to facilitate voice calls rather than conventional copper landlines. Many newer hybrid phone systems designed for large businesses come with VoIP compatibility, offering the adaptability to use both VoIP and traditional lines concurrently. For additional information, please visit our VoIP page.
Night bells or out-of-hours voice recording systems relay automated pre-set messages to callers during non-working hours or holiday periods. This system ensures customers stay up to date with your operating hours and other key details like after-hours support numbers.
Most modern PABX phone systems offer remote user connectivity, a feature that lets employees tap into the office phone system remotely to manage communications. By using IP phones and a reliable internet connection, remote workers can use the system to seamlessly interact with colleagues and clients when they are out of the office.
Manage communications for a large business with on-premise, hybrid or cloud PBX
Every enterprise has its unique interactions and needs, requiring a customisable PBX business phone system. We work with you to craft a tailored solution, considering your distinct needs to deliver the perfect PBX phone system.
There are several choices available for large businesses, each presenting its own capabilities, costs, and prerequisites for installation.

We provide expert advice and end-to-end implementation using premium hardware from top-tier brands like Yeastar, Yealink, NEC, and more.
Let’s delve into the PBX system options for large enterprises, specifically on-premise PBX systems (analogue and IP PBX) and cloud-hosted PBX systems.
On-premise PBX and hybrid IP PBX systems for large businesses
On-site phone systems can either be analogue PBX systems that use traditional phone lines, or hybrid PBX systems that utilise both phone lines and an IP network.

Cloud PBX phone system for large businesses
Cloud PBX, also referred to as hosted PBX, provides businesses with a fully-fledged enterprise-grade phone system that is managed and accessed via online portals or softphone applications.
Cloud PBX systems utilise a business’s internet connection/network, cutting costs related to line rentals, intricate installation of physical hardware, call charges, and more.
Hosted PBX phone systems are also packed with features, providing a suite of standard and advanced functionalities for managing voice communications.

PBX purchase options for large businesses
At United Telecoms, we offer flexible payment options for large-scale business phone systems. You can either purchase your PBX phone system outright via EFT or opt for a fixed-term rental.
PBX rentals and upfront purchases for large businesses
For an outright purchase, you’ll own the hardware immediately and could save on the overall system cost.
However, we often suggest renting, especially given the technical nature of large PABX phone systems.
With PBX rental terms, you’ll have a predictable monthly expense and always access to the best solution for your needs. Rental terms can range from 12 to 60 months, and we also offer short-term options.

Requirements for PBX phone system installation
The installation requirements for different PBX phone systems vary depending on the chosen type: traditional PBX, IP PBX, or Cloud PBX. To better understand the installation requirements for PBX phone systems, refer to our PBX installation page or contact us for assistance.
Necessary for traditional and hybrid PBX phone systems. The number of lines required depends on the desired number of users.
Analog PBX and hybrid PBX phone systems require a PBX main unit and other essential hardware components.
Properly connecting new or existing desk phones and base stations for cordless handsets to your PBX phone system relies on physical cabling that is set up within your premises. Physical cabling requirements may vary if you plan to install a cloud-based phone solution.
Location plays a vital role, influencing the choice of phone system and network solution that best suits your communication needs. Implementing a VoIP phone system typically requires a Fibre internet connection to provide reliable and high-quality communication.
Existing PBX handsets may be compatible with your system. Alternatively, you can purchase new handsets, such as analogue, digital, or IP phones, to effectively manage your communications. Handsets and peripherals must be selected based on their compatibility with your system and their ability to execute required functionalities.
