FXO recommendation in 2026

[InformatiqueJoskin]

Hello,

What is the current FXO device (not EOL) that is recommended ?
I've been looking at https://www.3cx.com/voip-gateways/ (which now redirect to https://www.3cx.com/sip-phones/) but I only see Granstream GXW4104 which isn't updated since 2013.
I've also looked at the Grandstream HT813, but I see on the forum that it doesn't seems to be supported nor working.

Thanks for your help,
Nicolas

Why not the Grandstream HT812, for example?

The HT812 is an FXS and not an FXO. I need to connect to my provider line and not to an analog phone.

Ah, sorry, my mistake. In that case, only the Grandstream GXW4104 is officially supported. However, nothing is stopping you from testing a more recent model. That said, I can't name one that is guaranteed to work, as we don't actually use devices like that ourselves.

Please note that 3CX no longer provides FXO gateway templates. As a result, 3CX doesn’t directly control or validate interoperability with FXO gateways. Compatibility with 3CX is handled by the gateway manufacturers themselves.

That said, FXO gateway integration is fairly standardized and doesn’t evolve much over time. It’s generally quite universal.


Important: The gateway must be local to the 3CX system, on the same subnet or on a locally routed subnet, including through a site-to-site VPN.


Although 3CX doesn’t directly support FXO gateways, it recommends the following manufacturers: Patton, beroNet, and Grandstream.


Since technical support for the gateway itself must be provided by the gateway manufacturer or vendor, the availability and quality of technical support should be an important factor in the purchasing decision.
