Not a local domain

Hi,

after upgrading from 1.6 to 1.8 all work’s fine… i recive only this error on 1 sip account:

chan_sip.c: Registration from ‘sip:user@’ failed for ‘x.x.x.x:5060’ - Not a local domain

Can someone help me ?

this is the user in sip.conf:

[clinicheodo]
type=friend
defaultuser=pippo
secret=pipposecret
context=visibile
callerid=0000000000

You need to provide domain name in the registration. I believe an empty string is a protocol violation.
