[SR-Users] Dispatcher Module ds_select_domain("2", "4")

[Alex Balashov]

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.
