[Serusers] Can SER authenticate to an "uplink" proxy?

[Nils Ohlmeier]

Hello,

this only possible with a B2BUA, but SER is no B2BUA.
Short explanation: for authentication the number in the CSeq header has to be 
increased, so the final reply for the authenticated request would not match 
with the original request from the UA any more.

Greetings
