1. Understand your business needs

  • Size: The provider you choose should be able to scale with you. Some services are tailored for SMEs, while others cater to larger corporations.
  • Global Presence: If your business has international clients or plans to expand globally, consider providers that offer international calling at reasonable rates.

2. Reliability and uptime

Choose a provider with a strong track record of uptime. Downtime can be expensive, both financially and in terms of reputation. Providers should offer at least 99.9% uptime.

3. Features to look for

  • Integration: Ensure the system integrates seamlessly with your existing software, like CRMs, email platforms, and team collaboration tools.
  • Mobile Access: As remote work becomes more prevalent, mobile apps or forwarding features are crucial.
  • Voicemail and Transcription: Accessibility to voicemails via email or transcribed messages can improve response times.
  • Auto-attendant: An automated system that can direct callers to the right department or person without human intervention.
  • Call Analytics: Understanding call volumes, durations, and peak times can help improve your customer service and streamline operations.
  • Multi-level Interactive Voice Response (IVR): This allows customers to self-select their path based on their needs, reducing wait times and improving satisfaction.
  • Call Recording: Essential for training, quality assurance, and compliance purposes.
  • Conference Calling: For team collaboration, especially if members are dispersed geographically.

4. Customer support

Reliable and readily available customer support can be a lifesaver. Check for providers with 24/7 support, preferably based in the UK for faster response times.

5. Reviews and testimonials

Existing customer feedback can provide insight into the real-world performance and reliability of the provider. Look for reviews that specifically address your concerns.

6. Costing and contract flexibility

Understand the pricing structure. Are there setup fees? How about costs for adding or removing users? Also, ensure there’s flexibility in the contract to scale up or down based on your business needs.

7. Security and compliance

Given the increase in cyber threats, it’s crucial to ensure your provider meets industry standards for security. Also, if you’re in a regulated industry, check for relevant compliances.


Selecting the right hosted cloud telephony provider is a combination of understanding your current and future business needs and ensuring the provider you choose offers the features, security, and flexibility to meet those needs. Always remember that the cheapest option isn’t necessarily the best one; it’s about getting value for your investment.
