[OpenSIPS-Users] multiple registration

[David Villasmil]

Thanks for answering.

     Yes, that's what I need. The new record should override the old one
(provided it comes from the same public IP) although this should be
configurable via script. I'm sure there is a way but I just can't figure it
out.
