Your wording would mean that a private listening mechanism, other than
2.5mm and 3.5mm jacks, would be non-compliant if the product "provides
auditory output beyond simple tonal feedback or signaling." Many of
Avaya's products provide private audio feedback about their status via
the telephone's handset. The wording you have proposed could cause a
contract officer to decide that our approach does not satisfy the
requirement. I hope you agree that this would be an inappropriate
I understand the point you are making, but question the underlying
assumption that a 2.5mm headset is the only private listening device
that anyone would ever use. I think that depends on the nature of the
product. Perhaps we can come up with wording that would limit the
requirement to products that do not have an inherent private listening
capability for the provision of status information.

That would solve a lot of problems but you need an amplifier to make
The RJ-9 connection is too low power to drive any headsets etc even if
have an adapter. ]
So it would require that users carry a batter operated RJ-9 to 2.5 mm
adapter with them. And at work the battery would keep running down.
Need some consumer input here.
