Fine, I found out where was the difference between sending from sipsak and from PJSUA. sipsak sent it from random port and PJSUA from 5060. When I changed the sending port for sipsak to 5060 and turned on symmetric routing (sipsak -vvv -i -S -l 5060 -f sipsak.msg -s sip:example.com:5060) my router rewrites private addresses to public as well. I forgot to write in earlier posts and didn't think that could cause the problems that my router is standard old PC box running Gentoo Linux as well. And that one rewrites the addresses. So it can be either iptables, or dnsmasq, or kernel or something else... :/ Does anyone here has experiences with Linux routers rewriting IP addresses in SIP (or maybe in any other protocol)? If so please let me know where to look for the problem. Many thanks in advance! Ondrej
