What about calling alias_contact() just in case
nat_test() detects the
following two requeriments:
1) The IP in Contact is private.
2) There is no ";alias" param in Contact URI.
Of course a new nat_test flag would be needed for point 2.
inaki,
the rule is: do not call alias_contact(), when request or reply comes
from a proxy. so even if there is no ;alias in contact, alias_contact()
must not be called when request or reply comes from a proxy.
the question is, is it possible to somehow detect it. for initial
requests, proxy can be detected based on existence of an rr header.
regarding in-dialog requests, perhaps that could be detected if proxy
adds into rr header an param telling that request came from a proxy.
it might then be possible to test that param in in-dialog requests.
lets think it more.
