A Guide to 3CX Professional Licenses
A 3CX Professional License takes 3CX Phone System to the next level and is great for larger businesses, call centres, or businesses that need to record calls. A 3CX Professional License key includes all of the Standard Edition features, plus several additional ones such as call queuing, video conferencing, and CRM integration. Here's a list of the best features in the professional edition.
- Microsoft 365 Integration
- CRM Integrations
- Video Conferencing for up to 100 Participants
- Call Queues
- SLA Alerting
- Switchboard
- Wallboards
A 3CX Pro annual license key gives businesses access to advanced phone system features, for much less than cloud-based phone systems that charge per employee. This is because 3CX licenses are based on the number of simultaneous calls you need to make and not the number of users. This means you can add unlimited employees, who will all have access to the Pro features. All 3CX license keys need to be renewed annually with a 3CX Partner.

We moved from BT to Zen Systems for our Telecoms and it's been fantastic. They helped us implement 3CX. The call quality is excellent and the system is incredibly user-friendly. Their customer support is always prompt and helpful, ensuring any issues are resolved quickly.
Highly recommend Zen Systems for any business looking for a reliable telecom solution!

Very knowledgeable 3CX service provider As a 3CX customer with a different service provider we were previously encountering very slow response times to issues raised, and an inability to correctly handle them when there were finally responded to.
This experience prompted me to switch to Zen Systems who demonstrated very clearly their expertise with 3CX. James Howard-Dobson and his team were extremely helpful in migrating us from our previous provider, responding with grace to challenges encountered along the way. I'm pleased to report that our service is now running very smoothly.

We have trusted Zen with our IT support for the last 8 years and have always found the team to be very willing and able to support on all our IT and telecom needs. We have had a number of office moves, system upgrades and rather challenging internal database integration issues, all worked through by the Zen team.
Particular thanks to Dean, always happy to help and calm in a crisis. A superstar!
