Your questions answered...
Do I need a 3CX system to use the apps?
Yes, to use our apps, you'll need a 3CX system. You've got choices: let 3CX host it for you in the cloud for a small fee or even for free. Or set it up yourself on your own server. Just know that the apps won't work unless you have a 3CX system in place.
What is a SIP Trunk - and why do we need one?
You need a SIP trunk to place calls to external numbers. You also need one to have a number on which your customers can call. To let you keep full control of your phone numbers and get best call rates, 3CX does not have built in numbers. But this freedom to choose means you’ll need an account with one of the supported SIP trunk providers.
Is 3CX FREE really free…forever?
Yes! 3CX FREE really is free forever - for up to 10 users. And once your business grows - scale up with 3CX SMB - Small Business edition. To start, sign up for your 3CX FREE account. Then select a SIP Trunk provider. This is where you’ll get your phone number from and where you’ll handle your phone bill.
Do you have help manuals for the 3CX apps?
Yes! We have easy to follow guides for our Android, iOS and Windows apps.
