[reSIProcate] Change the credentials of User after the Re-Registration Timer has started

["Roger Peter" <rpeter@xxxxxxxxxx>]

  When we send a register for the first time, we specify the time-limit
for re-registration. This Re-Registration is carried every timeout
specified by MasterProfile->setDefaultTimeOut(). This is done by
re-sending the last request after incrementing the CSeq no. So the
credentials are also same, as it is using the Digest generated
previously. So how can we change the credentials, or any other solution
by which the timer continues and the credentials are also updated.

Roger,
