In attachment are 2 stun test outputs (stun2.txt and stun3.txt)- if they
mean the NAT is symmetric - I don't know.
But see also stun4.txt - the port in mappedAddr differs for 2 different
STUN servers- also it seems to be a symmetric NAT.
BTW - Twinkle reports with pop-up warning also symmetric NAT.
Interesting is, that with Twinkle the echo test (500) works - of course:
the SIP server and called number (500) are on the same IP address.
The call to someone else would probably fail.
But Ekiga client do not get answer for his INVITE request ?! So Ekiga
fails calling 500 behind symmetric NAT.
