How many simultaneous calls do you need?

We can work with you to determine what’s best for your business. However, as a general rule of thumb, 1 simultaneous call per 3-4 extensions is sufficient, i.e. a company with 50 extensions would need a 16 sim. call licence.

Is the free licence actually free?

Yes. Annual Standard 3CX licences for 4 or 8 simaltaneous calls are free licence.  

That inlcudes unlimited extensions, iOS & Android apps and auto-provisioning.

To make inbound and outbound calls you will need to BYO or choose own SIP trunk and numbers. 

You can DIY setup, or set-up and support can be purchased. 

Upgrade at any point by paying the price difference and without reinstalling.

What are simultaneous calls?

Simultaneous calls are calls made concurrently at a given time.

Most businesses find they need the ability to make 1 simultaneous calls per 3-4 extensions.

Can I upgrade later?

Yes. You can upgrade your subscription at any point in time by just paying the difference for the remaining period.

What is a 3CX reseller?

A 3CX reseller is company authorised to provide 3CX products. 3CX does not
directly sell its own licences; they must be bought through a 3CX reseller.

We are a Platinum 3CX Partner and have been working with 3CX for 15 years.

Does my licence need to be renewed annually?

Yes. 3CX licences require renewal every year. 

If your licence expires you will automatically be downgraded to an 8SC annual standard licence.
An 8SC licence is a standard software as a service licence without the services included in the annual subscription.

3CX Pricing Guide

3CX pricing is based on the number of simultaneous calls your company needs to make and not the number of extensions or users. This includes internal and external calls. This makes 3CX pricing much more competitive than other phone systems that charge per user.

1 simultaneous call per 3-4 people works best for most businesses. For example, if you have 50 people, you’ll need a 16 SC license. If you’re unsure, buy your license using this ratio and you can easily upgrade it later if needed.
