Message Waiting Compatible analogue phones

[eveton]

Can anyone please recommend a make/model of compatible analogue phone handsets they use on the Definity G3r v11 as we are struggling to find "off the shelf" units that work with MW (Message Waiting). most types we've tried use either 2 or 3 MW modes being High Voltage, reverse polarity, or Voltage drop. Some work but with opposite logic i.e. the lamp is always on until message waiting is received then "winks" the lamp off/on. So far the only one that works correctly is the ATL Berkshire 200/400 etc. except that the tiny little LED is almost unnoticeable when alerting.
Any help would be much appreciated.
Thanks in advance.
Tony

Teledex phones is what AVaya was selling with their hotel locations in the past. I don't know if they still are.
But I have never heard any complaints about the lights not working on those.
