Hi Nils,
I agree that my example is not normal behaviour. But out of 100 users, I am
sure, at least one would experience multiple registrations due to dropped
dial-up calls. And modifying the UA agent as per your suggestions is really
beyond my control.
Thanks,
Ricardo

to configure
SER so that it only has the latest registration?
as Juha allready stated normaly the UA should unregister.
And to your example i would say this is not normal. If a user contacts minutes from another IP he should set the expires
value in its UA to value
so
that nothing goes wrong. I mean in reality i would not
expect that some
registers every 5 minutes from another IP. But if the user do it this way
he
should set the Expires value maybe to 7 minutes.
And the last choice would be that the UA unregister all previous
registered
contacts (for example on startup) and registers its
current contact after
this. But this should be an option for user who know what they are doing
(for
example an extra button which ask twice before
unregister everything).
And at last: the q value gives the user the chance to configure in which
sequence a proxy with forking should try to reach the user at the
different
contacts. So the user can configure that the proxy
should first try
contact a
and after this try contact b because of its higher or
lower (i'm currently
do
not know how the contacts will be sorted) q value.
