Connect Grandstream Gateway FXS to 3CX service

[jeff_jams]

Looking to deploy 3CX service. Setting up a system to test.
Looking for options to connect legacy phone equipment from old POTS setup.
Basically, I want one extension to ring out to a set of old phones using a FXS. I want to confirm this will work before purchasing the FXS Gateway equipment.

• 3CX Version: Professional Annual - 18.0 Update 8 (Build 939)
• 3CX Server Hosted by 3CX

I should add, it does not need to be a Grandstream FXS

I think I found my answer here:

Please note that the ATA must be provisioned behind a dedicated 3CX SBC, more info here

Thanks. And my understanding is that the Yealink T53W IP Phone can act as the SBC? Is this still true in this case? Or will I require the Raspberry Pi 4/Windows 10/Debian Linux setup?

Dedicated 3CX SBC for ATA.

For clairity's sake... that means that I will need to set up either the:

• Raspberry Pi 4,
• Windows 10 / Server 2016 and up, or
• Debian Linux

3CX SBC setup to achieve this. Correct?
