Comment #5 on issue 2173 by jean.deruelle: Handle Header [Authentication-Info: nextnonce="xyz"] in sip authorization responses
http://code.google.com/p/mobicents/issues/detail?id=2173

Actually. It would be more cache the credentials when they are passed ie when the request sent out gets challenged (so on the creation of the challenged request to a 401/407). So that the container can reuse the credentials to recalculate the response digest based on the nextnonce to build the next subsequent request without any input.

The process will be the following

INVITE/REGISTER sent by MSS app
401/407 received
INVITE/REGISTER with correct Authorization headers value and the app use the newly defined method to cache the username and password passed
200OK received with Authentication-Info containing nextnonce

MSS App sends subsequent requests which contains the correct nonce and digest based on the nextnonce received in the 200OK and username and password cached from the beginning.
