It could be the ATA device.
My provider sent me a free Linksys PAP2 POS. I got around to
hooking it up one day, and the line was all hiss and noise.
My normal gear worked fine, so I basicly chucked the PAP2 out the door.

They all support bring your own device. I suggest trying them out one by
one with a softphone until you find one you like (unless you already have
the hardware).

I use VoIP Stunt on a PAP2 ATA, VoIP Stunt and their sister services
don't sell/provide hardware, they get you to download their softphone
and list the SIP details required for using your own hardware, be it
ATA, VoIP Phone or router with VoIP ports, or you a SIP softphone of
your own choice.

My PAP2 is faultless, along with other people I know with the device,
it's an excellent piece of kit.

Indeed. I had a call from a friend in Arizona yesterday (I'm in the UK) on
my FWD number (routed from my US IPKall number) and she made a point of
asking me if I'd changed anything as the call quality was even better than
usual. It's always been at least as good as the PSTN, in fact nobody has
ever made any adverse comments on call quality on any of my several VoIP
accounts (with three different providers).

So you are able to make regular calls with your regular phone with
clear sounds? I am thinking about using my LINKSYS RTP router(same one
from Vonage) which has 2 phone ports. How did u set yours up? Thanks.

Sure, the company you use to get into the phone system can have a bad
SIP->PSTN gateway (either badly designed, badly setup or just broken).
Also, many VOIP companies buy their connectivity from some upstream.
It may well be that even after you switched you were still on the same
equipment. There could also be a problem at your end. Cordless
phones are notoriously bad. Some put out so much noise that any
compression the ATA does, has the compressor allocate most of the
available bandwidth to moving the noise. This doesn't happen with
POTS because POTS typically is uncompressed straight encoding called
ulaw. This is another good reason why you want any compression on the
SIP line. My feeling is it should be set up for straight ulaw.

That doesn't damn the whole SIP idea. It is just that they can't do a
good job of it. SIP when set up correctly is much cleaner than POTS.
There is less chance for noise to enter the system and the signal is
digitized much closer to the handset. The digitization method can
(and in my opinion should be) the same as POTS - straight ulaw.

There are some companies that allow you to bring and set up your own
equipment. Some have really decent prices (no monthlies if you just
want outgoing calls and 2cents/minute.) You can buy as expensive or
cheap a voip phone as you want. I have pay by the minute accounts
with both www.teliax.com and www.gafachi.com . Both are coming up on
two years now and I'm still very happy with both. (Anyone that knows
any other pay by the minute services please post! I'm always
interested to hear of alternatives.)

I have standard corded and a couple of DECT cordless phones connected to
the PAP2, I can call regular phones without any problem, the calls are
crystal clear, you wouldn't know I wasn't using a regular phone most the
times, the only times someone says anything is when they say how clear
the call is.

I don't have a regular landline, I have broadband, no phone line, and
use VoIP for all my calls, except my mobile for a few calls here and
there.

It was just a case of entering the SIP details onto the PAP2, and then
setting up a dial plan, so I don't need to dial the full number for
local calls etc.

I've been happy with voxee & voipjet for PAYGO.

I also suspect the SIP->PSTN gateway as being the weak link in the
chain. I think Allstream is the 3rd party here in Ontario, Canada.

In my case, I compared a call to the same destination with Vonage and
Bell (my office voicemail). When I stopped talking, I could hear hiss
and a high pitched carrier-like sound coming from the other end with
Vonage. I heard dead air with my Bell landline.
