Business Phone System FAQs

What is a business phone system?

Business phone systems provide the necessary framework for businesses to make and receive calls. They encompass a range of technology, from the key telephone system to the private branch exchange (PBX). Business phone systems ensure efficient communication between customers and employees by offering advanced features such as call forwarding, auto attendant, and voicemail, which in turn can increase productivity, improve customer service, and save money.

Business phone systems offer a wide range of features such as call forwarding, auto attendant, and conferencing that allow businesses to stay better connected with their customers whether in the office, at home, or on the go. Voice over Internet Protocol (VoIP) technology provides businesses with an efficient solution to manage all of their communication needs while keeping costs down.

Are business phone systems reliable?

Business phone systems are much more reliable than traditional phone networks, which is why thousands of businesses across the UK have already made the switch with Infinitel.

Our phone systems are hosted in a highly diverse carrier network, and each segment of our voice platform can continue operating even in the event of hardware or interconnecting outages. We are so confident of our infrastructure’s reliability that we offer a 99.999% uptime SLA.

If you do happen to run into any issues, the Infinitel team are available 24/7 to support you. Unlike most business phone system providers, we assign an experienced account manager to each of our customers who will constantly monitor your system to ensure everything continues to run smoothly and fix any issues before you even know about them.

How do you set up a business phone system?

By implementing VoIP and cloud-based solutions across your business, you can set up your own business phone system quickly and easily with minimal upfront costs. Our team will guide you through the set up process and are available 24/7 should you need any assistance.

What is the best business phone system for remote working?

All of Infinitel’s business phone systems are optimised for remote working, regardless of whether you choose direct routing for Microsoft Teams3CX, or CloudFusion. Our business phone solutions allow your employees to make and receive calls from anywhere with an internet connection and across any device, whether that’s their mobile phone, laptop or PC headset, or an IP phone.

What do I need to make a VoIP call?

To make a VoIP (Voice over Internet Protocol) call, all you need is a reliable internet connection and a device that will allow you to make and receive calls, such as a mobile phone/cell phone or laptop. A VoIP system can help your business to save large sums of money by dramatically reducing your office telephone bill and eradicating charges on international calls, plus your users will benefit from clear, high-quality audio.

Can I keep my business phone number when I switch to VoIP services?

As a business owner, you’ll want to keep the same phone number so that your customers can contact you quickly and easily without having to search for a new number.

This is why Infinitel’s business phone solutions allow you to easily transfer your existing phone number over to a new system, giving your business the continuity it relies on to maintain success.

Are there long distance charges for VoIP?

VoIP (Voice over Internet Protocol) technology has revolutionised long-distance calling by eliminating the long-distance charges that are associated with traditional landline telephone calls.

VoIP allows users to make free international calls from anywhere in the world as long as they have a stable internet connection, making it a much more cost-effective solution for business communication.

Is the quality of VoIP calls good?

At Infinitel, we guarantee the highest audio quality and an overall exceptional call experience for our users. We work with only the best service providers and manufacturers to ensure that our customers are provided with reliable, high-quality business phone system solutions that meet the needs of your business.

What is the difference between key telephone systems and PBX systems?

Key telephone systems (KTS) and private branch exchange systems (PBX) are both business phone systems used to manage communication between multiple phones. However, while KTS relies on user access codes, PBX systems use advanced technology to connect multiple phone lines.

PBX uses advanced features such as automatic call distributors and VoIP devices to control communication across your business, while KTS is not automated and does not rely on the latest technology.

What is SIP trunking?

SIP trunking allows businesses to make and receive voice calls directly over a data connection. Previously, the only viable method of providing business-grade telephone lines to a PBX was ISDN, which can be expensive and inflexible. By contrast, SIP trunking offers a cost-effective solution by connecting your VoIP system with a Public Switched Telephone Network (PSTN).

How secure are Infinitel's business phone systems?

Infinitel’s business phone systems provide businesses with a secure and reliable communication platform. We work in close partnership with some of the industry’s leading vendors and manufacturers including Ribbon, Fuse2, and Yealink to ensure that our systems will keep your data safe. Thanks to security features such as encryption, two-factor authentication, and advanced firewalls, you can rest assured that your private information is protected.
