Keeping your business phone system up to date with compliance requirements is essential to avoid unexpected disruptions, security risks, and potential fines. Rather than waiting for a problem to arise, it's best to review your phone system regularly—especially when there are changes in regulations, technology, or your business operations. This ensures your communications remain secure, reliable, and aligned with UK standards such as the Data Protection Act 2018 and Cyber Essentials.
Why regular reviews matter for UK SMEs
Phone systems, particularly those based on VoIP (Voice over Internet Protocol), handle sensitive customer and employee data. If your system isn't compliant with data protection and cybersecurity standards, you risk exposing personal information, suffering service outages, or losing customer trust. For example, a breach caused by weak access controls or outdated encryption could lead to ICO investigations and damage your reputation.
Moreover, compliance changes often come alongside new technical requirements—such as mandatory multi-factor authentication (MFA), enhanced call logging, or stricter supplier security assessments. Without regular reviews, your business might miss these updates, leaving you vulnerable or out of step with audit expectations.
A typical scenario for a UK SME
Imagine a UK-based company with 50 staff using a VoIP phone system managed by a third-party provider. After a Cyber Essentials Plus certification audit, they discover their phone system lacks proper call recording encryption and that user access isn't tightly controlled. This puts them at risk of non-compliance with the Data Protection Act and internal policies.
A proactive IT partner would identify these gaps during a scheduled compliance review, recommend implementing MFA for phone system access, update encryption protocols, and ensure call logs are securely stored and regularly backed up. This approach minimises downtime, protects customer data, and keeps the business audit-ready.
Checklist: When and how to review your phone system for compliance
- Review at least annually, or immediately after any regulatory updates affecting data privacy or telecoms.
- Check your provider's compliance credentials—do they follow UK GDPR, Cyber Essentials, or ISO 27001 standards?
- Ask about security features such as multi-factor authentication, encryption of calls and recordings, and secure access controls.
- Verify backup and disaster recovery procedures for phone system data and configurations.
- Request audit logs and access reports to ensure only authorised users access sensitive phone system functions.
- Confirm your provider's incident response plan and how quickly they can resolve outages or breaches.
- Review supplier questionnaires or tender documents to assess ongoing compliance and security posture.
- Test internal policies around password management, device security, and user training related to phone system use.
