Why Your Business Needs a Modern Phone System

For most organisations, the telephone remains the primary lifeline. It is the fastest path to your customers, the critical link between remote teams, and the voice of your brand. However, the landscape of business communications has shifted dramatically. Relying on traditional copper telephone lines, ageing on-site PBX units, and outdated ISDN services is no longer just a competitive disadvantage—it is an operational risk.

The way we work has evolved. The rigid “9-to-5 at a fixed desk” model has been replaced by hybrid working, hot-desking, and mobile agility. Legacy phone systems simply cannot keep up with this pace. They are expensive to maintain, difficult to update, and tether your staff to physical locations.

According to recent Ofcom research, over 1.6 million UK business lines still rely on the legacy PSTN network, despite the approaching 2027 switch-off deadline. The average UK SME spends £450 per month on telecoms—a cost that can be reduced by 30-50% through modern VoIP technology.

A Modern Business Phone System Transforms Your Operations

A modern business phone system from Stride transforms your telephony from a utility bill into a productivity tool. It allows you to:

Whether you are looking to upgrade old hardware to protect your investment or are ready to move your entire communication suite to the cloud, Stride makes the transition simple, secure, and risk-free.

What Is a Business Phone System in the Modern Era?

Historically, a “phone system” was a physical box screwed to the wall of a server room (a Private Branch Exchange, or PBX). It required complex wiring, expensive maintenance contracts, and an engineer visit just to change a name on a specific extension.

 

Today, a business phone system is a software-driven communications platform. While desk phones still exist, the “intelligence” of the system has moved to the cloud. Modern solutions utilise VoIP (Voice over Internet Protocol) to deliver calls over your internet connection rather than old copper wires. This shift creates a system that is infinitely more powerful, delivering High Definition (HD) voice quality, lower monthly bills, and smarter features that were previously only available to large call centres.

Key Features of a Modern Business Phone System

Regardless of whether you choose a fully hosted Cloud solution or a SIP-connected system, Stride ensures your business has access to enterprise-grade features. These tools are designed to enhance professionalism, improve customer experience, and streamline internal collaboration.

Smart Call Routing

Intelligent routing allows you to direct calls based on specific criteria (time of day, skill set, caller ID) to the person best equipped to help them.

Voicemail-to-Email

Systems convert voicemail audio into digital files and email them directly to your inbox for efficient listening, forwarding, or archiving.

Mobile & Desktop Apps

Turn any device into your office phone. Staff can make and receive calls while presenting the main office number, protecting their privacy.

 

HD Call Quality

Modern IP telephony utilises Wideband Audio (HD Voice) technology for conversations that are crisp, clear, and natural.

IVR Menus

Greet callers with a professional menu system (“Press 1 for Sales…”). This automates reception, reducing burden on staff and filtering calls.

Call Recording & Compliance

Secure cloud recording for training, compliance (e.g., FCA), and dispute resolution. Calls are stored safely for easy retrieval and playback.

Number Porting

Keep your existing business numbers (01, 02, 0800, etc.) with zero downtime. We manage the entire process with the networks on your behalf.

Scalable Users

Adding a user is as simple as clicking a button in a portal. You pay only for what you use, allowing you to scale up and down instantly.
