asterisk users - Mar 2005 - Sipura 2000 x dual g729 channels x other choices?

I found a thread [1] last month about the poor/crappy g729 quality on 
Sipura units. Anyone noticed an improvement or the quality is still poor?

If the Sipura firmware/g729 offers no quality yet, who else is offering 
a dual channel g729 ATA? I heard about Uniden, but I have no "reports"
about their ATA...

[1] Sipura g729 call quality to PSTN

Don't believe everything you read. There is nothing wrong with the sound 
quality of the G729 codec on the sipura devices.  The 2000 does not 
support both channels running G729 at the same time. This limitation has 
be fixed with there new product.  I forget the model number.  Most G729 
sound problems can be traced to busy or poorly designed networks.  Too 
much packet loss.  I'm a sip service provider and have seen everything 
with sip. Supura is the best product on the market today.

According to the small print in the bottom graphic:
http://www.sipura.com/products/spa2100.htm

The  SPA 2100 would give u 2 ports + 2 RJ45 as well as 2 G729

When I was placing an online order, I found this:
"support for two concurrent calls using the G.729 codec (in a firmware 
release expected in the first quareter  of 2005)" (sic)

The dual g729 is reality "now" or is planned for a near future? I
found
that the latest firmware is 2.0.5d, but no info about the features or 
when it was released (release notes only display a copyright notice of 
2003-2005).

Its a reality now.  As of version 2.0.5.  We have deployed hundreds of 
these and plan to deploy thousands in the near future.  We use G729 
almost exclusively.

Do you transcode g.711 to g.729 with * ?

If so how many concurrent calls have you reached?

Yes.  But we never stuff more that 4T1s worth of calls on a Dual Xeon 
3.6.  We know it can do more, but why push it.  We prefer to have SER 
loadbalance all calls among multiple gateways.
