      Security Level: None

Hi,
i think there is a problem with SIP privacy in from header. To be more specific, problem concerns fromdomain part of sip message. 

According to RFC fromdomain should be set to: anonymous.invalid

Unfortunately that only works when configuration for this peer leaves "fromdomain"  empty. In other case fromdomain is overwritten. I think this is why:

chan_sip.c

{code}
/* Allow domain to be overridden */
	if (!ast_strlen_zero(p->fromdomain))
		d = p->fromdomain;
	else /* Save for any further attempts */
		ast_string_field_set(p, fromdomain, d);
{code}

Earlier we have condition checking if there are any privacy settings on.
If fromdomain empty (in my db config for this peer) fromdomain is set to anonymous.invalid.

There will be no problem if we have any method to change fromdomain otherwise that through configuration.
