Hello,
it is not very clear -- is that the INVITE is replied with 4017 by one
server (A) and them the client is resending the INVITE with credentials,
but it gets to the other server (B)?
You say that the 407 is getting to the other server, which is rather
confusing how it may happen.
Cheers,
Daniel
