Migration from 3CX to freePBX, is freePBX an alternative

Hello,
I am a newcomer and have no experience with freePBX.
We have a lot of small customers, with telephone systems from 4 subscribers to 15 subscribers.
Most of them use the 3CX 4SC Pro.
This license is getting more and more expensive and the support is getting worse and worse by 3CX.
That is why we are looking for an alternative.
Is freePBX a possible solution here?

Greetings Arthur

Yes, you can replace 3CX with FreePBX.

Hi Tom,
OK, do you migrate some 3CX PBX Systems to freePBX?
Our Customer use Yealink or Fanvil Phones.
And the use VOIP / CTI Client on Windows and Mobile-Phone.
BLF and Ring-Groups is no Problem?
Regards Arthur

That can be arranged. Done a few migrations in my time.

Which CTI / VOIP Client do you use?

How is the feedback from your Customers?
What is better 3CX or freePBX?

I don’t understand in which case a need a licence for the freePBX.
And how can I get support from Sangoma?

Are you asking just out of curiousty?

Just fine.

In what regards? I’m not a fan of 3CX in general.

There’s various ways. They offer support contracts if you want long term support overall. But depending on what it is exactly the support may be included or paid.

No, the CTI Client is important for our customers.
And some users onyl use VOIP Client on Windows or Mobilephone.

So you need soft phones. I use Bria myself but there is the Sangoma soft phone for mobile and desktop.

Did you need any license in your projects?

That is a case by case thing. Yes and no.

I assume you mean did you have to hand over any consideration for the licence (whether monetary, or something like the right to be bombarded with advertising). Nearly every bit of software requires a licence, that that is certainly true for the open source parts of FreePBX.

(There is an argument that only the supplier of software needs a licence in the USA, but in many other countries, you need a licence to store it in your computer, and to copy it into working memory.)

Oh, sorry, I mean the Addons
I don’t understand them.
Conference, Parking, Caller ID Management for example is Asterisk default.
