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.
