This package contains a set of utilities for client side Authentication Challenge handling. It has been adapted from the SIP communicator project and generously dontated to the JAIN-SIP project It is not part of the standard JAIN-SIP implementation at this point but is being considered for addition as this is an operation that is commonly required by all SIP clients; it is hence a good capability to include in a library such as JAIN-SIP.

Primary authors of this code are Emil Ivov with corrections from Jeroen van Bemmel.
