[asterisk-users] Asterisk on Rackspace, My SIP phone behind NAT

[SamyGo]

Hi,
Asterisk is quite good with resolving the NAT issues specially the kind of
issue you are facing ,as I see it, shouldn't be a problem. A few steps you
can troubleshoot  this problem.

1-a:Are your SIP packets from PC/SoftPhone reaching the server !! On
Asterisk CLI execute "*CLI>sip set debug on" - are you even able to ping
your server.
1-b: check if you've iptables ON on your server? "iptables -L" if its ON
then you just flush it "iptables -F" and then see packets reaching your
server !

2- If packets are reaching , do your phone registers successfully ? or it
becomes unreachable soon after it says it is registered on asterisk console
?
3- If your phone registers successfully and you are able to make calls, but
unfortunately calls drop after 30 seconds, then your asterisk maybe sending
packets back to your Private LAN IP directly (which of course won't ever go
anywhere) . then "externip" and "localnet" settings will help you.

These basic steps should get you rolling.

BR
Sammy
