I have 2 polycom 330s at a remote location, and one PAP2T ATA for fax.
Both phones register and can make calls out, however three items including the ATA wont answer, if u pick up the phone, or click on the answer soft key the phone just keeps ringing, you can click ignore or reject and it works, however both phone and the ATA refuse to answer a call.
What am i doing wrong?

One way to make sure it isn't NAT or your NAT router -- is to set the real IP of your net connection in the phones.. now I don't know the polycom but the Grandstreams in the advanced section I could put in the real IP of that connection I had the phone on and that would resolve it.. telling me
it was a NAT issue.
In my case I just called the provider and put the modem into bridge mode.. some of the provider modems out there don't play well with SIP.
There hasn't been a single location I could NOT get one of my phones to work.. and each time it was something related with NAT or UDP and scrambling of the UDP ports.
I hope that helps... or puts you on the path.

I understand about the NAT however what i forgot to mention is that it worked for the first 12 hours or so.
Here is my complete set up
Onsite
T1 in from my provider to a Smothwall, smoothwall to switches, switches to Trixbox.
Offsite Location
Phones to a switch and to a shared T1 with other tennants in the building. I have not looked at the equipment onsite as of yet, however other users in the building have used Packet8 so i cant see SIP being the issue, or NAT? I could be wrong.
Is it possible that if the connection offsite has a bandwith dropping due to high traffic it would not allow the phones to answer? however it would allow them to call out?

The phone will have registered with the server thus operning the port. After 12 hours the port shut and that stoped all incoming calls, you'll need to add the following line to your phone config:-
reg.1.server.1.expires="30"
That will keep the port open, if it took 12 hours to break you could increaser the number (not sure what the maxiuymum is though)
I would agree with that, however I replaced both phones with new phones and they never answered the incoming calls. They still did the same thing. Wouldnt a reboot of the phone or new phones cause them to reconnect and answer for the next x amount of hours?

However based on my exoeriences over the last few days (long story) i would reboot the router to empty any nat table in it and then reboot the orginal phones, that would completly discount my theroy if it didn't work then, at which point I'm lost!
I have lots of experience with pfSense and I can tell you for sure -- is it is scrambling the ports (as it does for all) for your audio and most providers and trix don't work well with this. Goto your NAT - Outbound and change it to manual -- then edit the rule it creates -- making the ports static. this resolved the same problem for me.
Another thing you want to do is to change the default ports on your phones from 5060 to anything else.. and not all the same as it also will only allow one state to transmit per port. I have gotten up to 45 phones (most recent install) to work perfectly through pfSense..
I use pfSense because its shaping is awesome and it flies when it comes to packet routing.

Im not using pfsense. Im using smoothwall. The phones register and voice passes, but the phones just wont go off hook to answer the call.
what allows the phones to go off hook? do you really think its the smoothwall?

Ok , i have put a pfsense firewall up, per your recommendation, and same issue..........
