Hi! By lloking at de doc, I understand the place to configure the STUN settings is the UAConfig object, by indicating stun_domain or stun_host. I tried both but it's not working, since I can't see the STUN queries using Wireshark. I did the same using Twinkle, just to check that stunserver.org was working, and I did see the queries... So, is STUN working with new python bindings or am I doing something wrong? Thanks in advance!! -- Sa?l -- "Nunca subestimes el ancho de banda de un cami?n lleno de disketes." ---------------------------------------------------------------- http://www.saghul.net/
