Not sure on your reason for this, but I can tell you that I have a Grandstream connected to a 60s rotary phone and it rings just as strong as ever. https://studio.youtube.com/video/r88JcZQE3B0/edit On Thu, Mar 24, 2022 at 2:35 PM Mike Hammett <voiceops at ics-il.net> wrote:
I'm looking for ATAs that produce a 90-volt ring. My Zhone only does 40v and my Grandstream only does 52v. It looks like the Cisco SPA122 used to, but it's EOS.
