HT801 without SBC

[greatchoice]

Anyone have luck getting the HT series connected without a SBC?

Sure, you can connect any SIP compliant device to 3CX, it's just a manual config. You just can't connect it as a FXS/FAX device since those are hard coded to not work via STUN/direct SIP.

As Cobaltit said, you can connect it via the extension credentials and IP of the PBX as your proxy/domain. You will want a static IP on the PBX.
