I too have the same problem on a few units, but not on others. I also
have been having difficulty hooking up multiple lines from one Sipura
to the same multi-line phone system (seems to create a line cross) but
have no problems with either cisco or dlink boxes. In general they are
nice units, but I suspect they may have had a batch go out that were
"noisy".

I hear the exact same noise on 2 units I purchased a few months ago.
I've been in contact with sipura support and they are willing to try
RMA'ing one of my units.
As soon as I can get to the site with the sipura, I'll be sending it
in.
I'll post my results to the list.
btw, I'd have to agree that its not comfort noise, its very similar
(only much louder) to the "hiss" that the old digium fxs modules had
on the tdm boards.

Not really a comfort noise. I say anything and it doesent go away. It
sounds like a shielding issue. I have tried to relocate the unit but
it
doesn't seem to help.
