Update: 6666/7 are the IRC ports which are blocked by my upstream provider. Thus, stun.pjsip.org is working fine - the problem was with my upstream provider. Nevertheless there is still a bug in pjsip as its get confused by this. regards Klaus PS: Wouldn't it be smart by pjsip if random ports never uses 6666 or 6667 as those ports are very often blocked by ISPs.
