Here's a few things that I do and it always works for me: - use a STUN server under the SIP tab (any public server will do, for example stun.softjoys.com), set Substitute VIA Addr: to yes and STUN Enable: to yes - change the default registration time under Line 1 and Line 2 from one hour to something like 3-5 minutes - also Under Line 1 and Line 2 set NAT Mapping Enable:to yes and NAT Keep Alive Enable: to yes - on the Asterisk server, for each one of the peers where you have a remote ATA, make sure you have nat=yes qualify=yes
