I have a NT136 and a NT265 connecteded over the internet which have been working perfectly for over a year. I wanted to get add new NT265 but my supplier told me they are discontinued and the replacement is the NT321. So I get the NT321 and on connection the dislay reads BAD PBX VER. So I upgrade the PABX from 3.2 to Ver 5, Upgrade the IPEXT16 card firmware and software and the phone display shows the time, buttons work but no Audio. My question is does anybody know why the NT136 still works perfectly but the NT321 doesn't. What is the difference?

I've just found 10,000 ways that won't work.”
