I would assume a NAT issue as well. There are routers which according to 
Ekiga's NAT detection change their role, my Fritz!Box e.g.. In the -d 4 
logs look for the lines containing stun. When I am continously starting 
Ekiga and make calls Ekiga detects cone NAT. The first time or after 
some inactivity it reads port restricted NAT.
