Actually, VoIP works very well, at least with my provider. I've got
PacBell/SBC ADSL at home (384k down, 128k up, although down bursts way
beyond that). Right now I'm using an 827 with an IPSEC tunnel into a
customer's office where they have a Cisco CallManager cluster, and gateways
out to their ISDN PRI and other branches with FXO POTS access. During the
setup we initially used public IPs (VoIP doesn't work through NAT presently)
and my 1605R and tested and using G.711 it was a little choppy at times.
Once I got an 827 and we got G.729a compression turned on, it now sounds
great (I think the 827 is either faster and/or having it directly connected
to my ADSL cuts out one more device (the ADSL Westell bridge I have)). QoS
helped as well (vs. all the other outbound traffic at my office), and
tunneling actually helped more (bypasses the firewall on both ends). I can
call out 18 different locations as a "local call" and it sounds great
(they're using FR internally between sites).
We're working on getting a few copies of CallManager for our own lab use
(that can install on any box), and when I do I'll put up some info on how to
connect for those that want to try (IPSEC tunnel first, then using Cisco's
IP SoftPhone on your PC).
I actually spent about 3 hours cleaning up my home rack last night (doesn't
have threaded holes, so I had to get more nuts and bolts to mount devices),
and when my Wife walked in, she couldn't believe it was the same equipment
all still connected (all the wires are hidden by wire management). We took
some pictures "before" and "after" and I'll post them when they get
developed.
