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
