SIP peer registers with one server, then later registers with another server,
SIP realtime caching could be an issue, unless of course the registrations come
from the same port (if behind NAT) and address, which is not likely in cases
where the SIP users are behind various NATs.</span></font></p>

does that SIP user now get cached on the originating server as well as the
registration server?</span></font></p>
