What kinds of IP phones are you using?
If you have POTS connections waht devices are you using?
We have tried to use a couple of different IP phones, but
they would only talk to the same brand using their internal
gatekeeper software.
The cheap phones I like the best are the grandstream budgetone (around
$65). I also have a supra spa-3000 for answering the POTS line and
taking messages. (my motto: anything worth build is worth
over-building. ;-)) I also have sipura spa-841, but the audio path is
very noisy. I haven't had any show-stopper interoperability problems
that a bit of playing with the options settings couldn't fix. I do
use ulaw (standard US phone) encoding so that may help. Every phone
and VOIP provider seems to do ulaw even if it may not be their
preferred encoding.
OB open-source: these phones follow the voip rfc's and can talk to
open-source sip phones (unlike the proprietary stuff like skype which
is in a world to itself.)
