One annual licence sized around business call capacity
One Annual Licence
Pay for a 3CX system rather than monthly licences for every user. Licence price is determined by the edition and SC size you select.
Size by Sim Calls
Choose capacity for the number of calls your organisation expects to handle at the same time, with room for busy periods and growth.
Basic, PRO or AI
Match the feature set to the job, from core business telephony to contact centre tools, integrations and advanced AI capabilities.
Host It Your Way
Deploy with 3CX hosting, in your own cloud account or on-premise. Select the operating model that fits your IT requirements and budget.
BASIC
Core Business Telephony. For organisations that need dependable calling, routing, apps and essential reporting without contact centre, CRM or AI features. Basic supports 3CX-hosted, self-hosted and on-premise deployment.
PRO
Contact Centre and Integrations. For growing businesses and customer-facing teams that need call queues, CRM and Microsoft 365 integrations, advanced reporting and AI voicemail transcription. PRO also supports multi-site and more advanced administration requirements.
AI
Advanced Automation and Insight. For high-call environments that need the complete 3CX feature set, including AI Agents, full call transcription, summaries, sentiment analysis, advanced analytics and resilience features such as failover.
Size the system, not every user
Many business phone systems charge for every user, every month. 3CX licensing works differently. Commercial editions are sold as one annual system licence, sized mainly by the number of simultaneous calls your organisation needs. A sim call (SC) is any internal or external call taking place at the same time.
User count doesn't set the licence price, but each SC size has published recommended and maximum user or extension limits. The right licence must account for both call demand and system size. For example, 50 users do not require 50 licences. If the busiest period needs 16 concurrent calls, assess a 24SC licence to provide additional capacity and room to grow.
One annual licence + edition + SC size = one 3CX system.
Fair Use Policy
System-based pricing does not mean unlimited users or extensions. Each SC size has a recommended range to guide sizing and a maximum permitted number. The maximum is a hard limit for that licence size.
Freedom Of Deployment
You can deploy 3CX in three ways: Hosted by 3CX, where we manage the hosting; self-hosted, where you manage it in your own cloud environment; or on-premise, where you run it at your own location.
Vendor Flexibility
With 3CX, you can choose from a wide range of supported IP phones and SIP trunk providers, giving you the flexibility to use the vendors that best fit your business.
Your 3CX licensing questions answered...
A simultaneous call is a call taking place at the same time as other calls on the system. Both internal and external calls count towards the SC capacity. An idle extension does not use SC capacity.
No. User count does not directly set the commercial licence price. However, every SC size has recommended and maximum user or extension limits, so the selected licence must still be appropriate for the size of the system.
Estimate the busiest period and count the internal and external calls likely to be active together. Include queues, outbound campaigns, conferencing and seasonal peaks, then add sensible headroom for growth. A 3CX Partner can validate the final size.
The recommended range helps match typical user counts to an SC size while maintaining suitable capacity and availability. The maximum is the highest permitted number of users or extensions for that licence size. Higher call demand may require a larger licence before the maximum is reached.
They are selected separately from the 3CX system licence. You can bring your own supported SIP trunk and numbers. Provider charges and partner services depend on the supplier and deployment.
