Is there any decent, not bank breaking, SIP ATA's out there that can

more than one phone line over voip?
Say we have a small office and want to just use basic phones. Have a
SIP
server already out there that we can connect to on the net

Might be a good thing to check with the ITSP though...
I've got a couple options.
Option 1 - Just buy IP phones and use those. Have all of them talk to the
SIP provider and be done with it.
Option 2 - Buy a VoIP appliance (there are lots of different ones) with
enough analog jacks for your phones (or maybe a mix of analog and digital
phones) and
ITSP's SBCs are smart and realize that these devices are connecting
from behind the same IP... Firewalls that actually touch the SDP/SIP
messaging usually break this, so disable it...
I've rolled out thousands of hosted IP handsets that work just fine in
these circumstances... The only real
advice! :-) Good luck!!
