Purchase options for business phone lines, SIP & VoIP Phone Systems
At United Telecoms, we offer flexible payment options for business PBX systems. You can either purchase your phone system outright via BACS payment or opt for a fixed-term lease.
SIP & VoIP system fixed-term rentals and upfront purchases
Purchasing equipment outright through a BACS payment enables businesses to take immediate ownership of their hardware and potentially save on the total cost of the system.
Choosing to lease the equipment affords businesses the chance to sidestep substantial one-time payments while enjoying increased flexibility in terms of upgrades, expansions, and maintenance.
Lease terms for VoIP & Cloud PBX systems may range between 12 – 60 months depending on your requirements and budget. Short-term leasing options are also available.

3. How do I get a virtual business phone number?
Getting a virtual business phone number involves selecting VoIP or cloud-based phone service (such as United Voice Cloud Hosted PBX). This type of service allows you to choose a number that is cloud-hosted. You can then make and receive calls over the internet, using either a physical IP handset or a software-based phone on your computer or mobile device.
4. What is VoIP and what does it mean?
VoIP stands for Voice over Internet Protocol. It is a technology that allows voice communications to be conducted over the internet. VoIP provides a wide range of features for managing voice communications while reducing costs, improving scalability and much more.
5. How does VoIP work?
VoIP works by converting voice signals into digital data and transmitting it over the internet. It allows you to make calls directly from a computer, a VoIP phone, or a traditional phone connected to a special adapter. It offers a number of benefits including lower costs, enhanced functionalities, and the ability to handle more than just voice calls.
6. What hardware do you need for VoIP?
For VoIP, you’ll need a broadband internet connection, a router, and a VoIP-enabled phone or softphone extension to make and receive calls.
Some businesses may also require a VoIP gateway if they have traditional phone systems in place.
Requirements for business telephone system installation
Installation requirements vary depending on the type of phone system you choose, such as a hybrid IP PBX system (SIP trunk), or a cloud-based phone system.
We explore the installation requirements in detail for these solutions on our PBX installation page and you can reach out to us for further assistance.
Physical phone lines: Required for a traditional phone system and hybrid PBX systems. The number of lines you’ll need depends on the number of users required.
Hardware: For analogue PBX systems and hybrid PBX systems, you will need a PBX main unit and other essential hardware components.
Cabling: Desk phones and base stations for cordless phones require proper physical connections to your PBX system, which requires correctly laid-out cabling within your premises. The extent of your cabling needs may differ for installing cloud based phone systems.
Location: Location is a crucial factor as it can influence the type of phone system and network solution that best suits your communication needs. If you’re implementing a VoIP phone system, you will need to utilise a reliable internet connection (broadband or fibre) to facilitate communication.
Handsets/peripherals: Existing PBX handsets need to be compatible with your system or new handsets can be purchased, such as analogue, digital, or VoIP phones, to help manage your communications. Handsets and peripherals must be selected based on compatibility with your system and their ability to manage voice communications.
