This is not always easily doable, due to NAT issues.

If some SIP phone is behind a NAT gateway, another Asterisk server
(different from the one having received the registration) won't
necessarily be able to reach the phone behind the NAT. Thus the whole
SIP registry shall not be directly shared, but calls should be
forwarded from one server to another, using existing registration
info.

Or another, possibly simpler solution is to set users to different
servers based on their login or something.
