Hi
i've a problem with MSN. When I try to subscribe my user with MSN
(4.7.2009) ser doesn't autorizie me, but when I try with kphone and the
same user, it works correctly. In fact I can see on contact table the row
of my user.
I have exported SIP_DOMAIN=sip.quellidelpirana.it
I think that the condition if (uri==myself) doesn't match my IP address.
any idea??
this is my ser.cfg.
