Hi Alex,
it's because i can see that kamailio (5.0.1 (x86_64/linux)) is already
successful connected to our Provider via kamailio uac module.
I can also see that kamailio send a refresh auth to 5.9.87.18 from time to
time.
Would the Provider answer with:
U 5.9.87.18:5060 -> 130.255.76.95:5060
SIP/2.0 100 Trying.
in any case if the auth was not successful before?
Cheers,
Georg
I'm not sure why you would immediately jump to the
conclusion that you
need to rewrite the To header.
This is just a normal 407 challenge. The first and most straightforward
interpretation is that the provider expects you to provide digest
authentication credentials, or that they don't have your IP in their ACL
and are falling back to a digest challenge as a default behaviour for
that reason.

Hi,
after Kamailio did a correct (INVITE sip:089321608@5.9.87.18 SIP/2.0
looks
good to me), to our Sip-Provider we get:
"SIP/2.0 407 Proxy Authentication Required."
Could it be that i have to rewrite also the following line:
To: <sip:089321608@sip.heissa.de>.
To: <sip:089321608@provider_from_dispatcher_table>.
and how can i do that?
Until now i use just ds_select_domain("2", "4")
Thanks,
Georg
