Quick Comparison: Leading VoIP Providers for UK Remote Teams

RingCentral Ultimate: Top VoIP for Mid-Sized Teams and Software Integration

RingCentral Ultimate Overview

RingCentral Ultimate is a fully-featured cloud-based VoIP system tailored to businesses that require flexibility, advanced features, and strong cross-platform integration. It supports seamless remote work and is particularly valuable for companies with hybrid or distributed teams, where reliable internal and external communication is critical.

Strengths and Weaknesses

A major strength of RingCentral is its unparalleled compatibility with over 400 third-party apps including Salesforce, HubSpot, Slack, Microsoft Teams, and Zendesk. These integrations streamline communication by embedding call functions within existing workflows. However, its premium plans come at a higher cost and do not include unlimited minutes, which might not suit all budgets or high-volume outbound teams.

Key Features

RingCentral Ultimate includes advanced call management tools such as custom call routing, multi-level auto-attendants, voicemail transcription, and call flipping – enabling staff to transfer live calls between devices without interruption. The platform also offers real-time analytics, call recording, barge/whisper features for training, and team dashboards for performance tracking.

Pricing Breakdown

RingCentral Ultimate starts at £29.99 per user/month for individuals. For businesses with 2–19 users, the cost drops to £24.99 per user/month, and for larger teams of 100 or more, the cost goes down to £22.99. A more basic entry-level version is also available starting from £12.99.

Who It’s Best For

Strengths and Weaknesses

Its strongest selling point is unlimited calling to 48 countries, helping teams maintain constant contact with clients or colleagues abroad without worrying about minute bundles. It includes native team messaging, call recording and secure video meetings. The interface is slightly less user-friendly than other platforms like RingCentral, and CRM integrations are not as extensive.

Key Features

Core features include HD video conferencing, team chat, call analytics, voicemail transcription and call handling tools. The X Series plans include skills-based routing, presence detection, and integrations with tools like Microsoft Teams and Google Workspace, offering a unified approach to communication.

Vonage Business Communications is known for its high level of customisation, particularly around CRM connectivity and call handling. Vonage Premier is a great fit for businesses that prioritise customer engagement and require specific workflows, such as sales departments and inbound support centres.

Strengths and Weaknesses

Vonage supports integrations with Salesforce, Microsoft Dynamics, HubSpot and other CRM platforms. Its interface is clean and functional, and users can quickly change routing rules or create new call groups. However, some of the advanced features (like analytics dashboards) are not available in the basic plan and require paid add-ons. It also lacks built-in video conferencing in the lower tiers.

Dialpad stands out for its use of artificial intelligence to enhance user experience and decision-making. It’s aimed at teams that want real-time insights from their call data, and suits remote companies who want to stay agile, informed and well-connected.

Strengths and Weaknesses

The standout feature is its Voice Intelligence (Vi) technology, which transcribes calls in real time, detects sentiment, and summarises discussions automatically.

Strengths and Weaknesses

The platform’s main advantages are its low price point and its plug-and-play design, which means no expensive hardware or setup time. UK-based customer service is available to assist with onboarding. On the downside, it offers fewer integrations and lacks advanced analytics, making it less suitable for large or fast-scaling teams.

Key Features

Included tools cover call routing, voicemail to email, mobile app access, number porting and a virtual receptionist. These core features are enough for most small teams who want to manage customer calls professionally.

Pricing Breakdown

What to Think About Before You Decide

Before committing to a VoIP system, it’s important to evaluate your business’s specific needs, technical environment, and growth plans. Here are the key factors to consider when comparing VoIP providers for a remote or hybrid setup:

Integration with Existing Tools
Make sure the VoIP system integrates seamlessly with the software you already use, such as CRM platforms (like Salesforce or HubSpot), helpdesk tools (like Zendesk), or collaboration apps (like Microsoft Teams or Google Workspace). This can improve workflow efficiency and reduce the need for staff to switch between platforms.

Scalability and Flexibility
Look for providers that offer easy scalability so you can add or remove users as your business changes. This is particularly important for growing businesses or those with seasonal staffing needs. Consider whether the provider offers short-term contracts, pay-as-you-go options, or flexible licensing models.

Support and Customer Service
Check whether the provider offers UK-based customer support and what their hours of availability are. Remote teams depend on reliable tech support, especially if staff are spread across time zones. Some providers offer 24/7 support, while others may only operate during business hours.

Call Quality and Reliability
Assess whether the provider guarantees a minimum service uptime (e.g., 99.999%) and what kind of infrastructure supports their platform. Quality of service is crucial for customer-facing roles where dropped calls or poor audio could impact your brand reputation.

Pricing Transparency and Total Cost
Understand all pricing elements, including hardware, setup, licenses, international minutes, feature add-ons, and cancellation terms. A low advertised rate may not reflect the true cost once extras are added.

Security and Compliance
Check for features like end-to-end encryption, GDPR compliance, and options for secure call recording. This is especially important in industries with data privacy obligations such as legal, healthcare, or finance.

By thoroughly reviewing these areas, you can choose a VoIP system that doesn’t just meet your needs now but also supports your long-term strategy.
