I have 2 SPA-841s and an SPA -3000. I have found that setting
"externip" to be usefull, but what really helped the most is to set the
SPAs to use distinctly different ports. SPA841(#1) uses ports UDP
5066,5067 and RTP 16391-16393. SPA841(#2) uses UDP 5068,5069 and RTP
16395-16397. Finally I have the SPA3000 on UDP 5070 and RTP
16399-16401. I don't use STUN (tends to cause more problems then it
solves).
On the Server side I have the NAT firewall/gateway forwarding UDP port
5060 and RTP 16393-16401 to *.
In sip.conf set "nat=route" for each NAT client.
Hope this Helps,
Mark Coccimiglio

Does anybody have a good link how to connect Sipura with Asteriks, both
behind NAT? I'm using FWD but their connection is like a weather
(especially IAX), I need something more reliable.
I was thinking of using stun and/or proxy but can not find any good link
explaining how to setup Linux server
