Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

NMPBX is a UK cloud VoIP business phone system for small, mid-market and enterprise teams, including organizations with around five users and larger multi-site operations. It combines core business calling with auto attendant menus, IVR, call queues, hunt groups, number porting, voicemail transcription, recording and softphone access. The service supports cloud, desktop and mobile deployment across web, Windows, macOS, iOS and Android, with API access for broader system connections.

Pricing is offered through two paid plans. Unlimited costs £3.10 per user per month when billed monthly and includes UK landline and mobile calls, AI transcription, sentiment scoring and all features. Pay As You Call charges calls as used while also including AI transcription, sentiment scoring and all features. This gives teams a choice between a monthly per-user option and usage-based calling. The feature set extends beyond basic telephony with searchable call recording, semantic search across transcribed calls, voicemail-to-email transcripts and a live wallboard showing call activity.

NMPBX fits teams that need UK business calling alongside structured call management and AI analysis. CRM connections include Salesforce, Zoho, SugarCRM, SuiteCRM, ConnectWise, Zapier and Outlook, while the phone-system API supports additional integration work. Geographic, non-geographic, freephone and international number porting are supported, and the service runs in UK data centres. It may be less suitable for buyers who require a free tier or 24/7 support. Teams prioritising email and phone support, GDPR coverage, mobile apps and call intelligence should find the feature mix more relevant.
