Maybe Andrew didn't get it....

It's Voice Codecs over ATM -> i.e. AAL1/AAL2 over DSL/ATM PVCs
terminated in ATM. There is No IP carrying the voice here. I clearly
didn't say VOIP.

The box the Telco provides can also do VoIP as well which is annoying
because customers can never know what gets provisioned. So it could be
VoIP if the Telco is lying and ripping of all their customers [not
likely],  but for the purpose of informing the users can you show that
you clearly acknowledge what kind of technology we are talking about
here.

Can you please acknowledge that it's not VOIP and post again your
opinions about running fax services using AAL2, specifically its own
fax relay protocol (something like T.38). Can you refer it to someone
else at mainpine, like in the US office (not the UK) if you don't feel
qualified to comment on VoATM/VoDSL.

Have you tested what modes that IADs operate in and how they effect
V.34 fax support - which I believe is your products main selling
point?

Please confirm what I'm pretty sure that fax works fine over CBR 64k channels,
The IAD's data sheet says "fax support - V27ter V.29 - NOT V.34, G3 &
G4 data". So it is going to cap V.34 mode. This is a very common
device in Australia that many businesses are taking up according to
it's proponents.

I can see why the Telco is a fan of it due to political issues with
telecoms trying to pay less for access to the copper wires (ULL) from
the former monopoly holder - or just rent less PSTN lines. I'm trying
to tee up to V.34 fax machines modems for a test tomorrow....

Cheers,

Luke
