This is in a STUN environment.

We bought an Algo 8180. We've gotten it to ring when it is supposed to, but unfortunately, it also rings at other times (no call log around the time of the ring). I encountered this before on Polycoms, but I can't figure out how to restrict the Algo to only talk to the configured SIP server.

I bought a Grandstream GSC3505. Easy to provision (once I figured out that DHCP options override what you manually configure for a provisioning server). The speaker on it isn't much louder than a regular ringer, if at all.

The Fanvil IW30 appears to be End Of Life, but I don't know why or what limitations I would encounter.

The Snom PA1 is EOL for weak cipher support.

What's left?

The Fanvil PA2\PA3 maybe, but then I gotta figure out a speaker. Fanvil offers an accessory kit that includes a speaker, but that then comes with a bunch of stuff I don't need (microphone, camera, etc.). Are PA speakers just all the same, and anything I get will work?
 
Another downfall of the GSC3505 is that the settings you need to set to be a ringer (as opposed to a PA) are overwritten by 3CX when the device reboots.

The Fanvil seems to retain the correct settings through reboots and power cycles.

The Fanvil IP discovery tool doesn't work.

Both Grandstream and Fanvil ignore configured provisioning settings (at least by default) and use whatever is sent via DHCP. Normally great, but not so great when I wanted to steer to my lab PBX.

I did add a $30 speaker from Walmart.com to the Fanvil, and it seems to work well.
