Hi, I am using the exact scenario you are using (As5400-asterisk-ata's). But I have not reached to fax issue yet. I tried codec g729 for voice call, it is not working. I think you have to buy g729 from digium.
Since both my Asterisk and SIP clients are in different NATS , I have to do the painful part of port forwarding for every client. Specially if I have more then one client on same NAT, what needs to be done. Voip-wiki suggest using SER or STUN. Can SER and MyStun can be installed on same Server where Asterisk is residing. Will somebody suggest anything.
