The problem occurs in the subscribe message, I believe.  The phone sends
it's subscribe message to whatever server it's registered to, so only
that server will know about it.  I know D. Garstang has done a lot of
painful work on multiple clustered asterisk servers attempting to do
stuff like this with SER, but we haven't done anything to that extent
yet.  There are probably a number of code modifications we could make to
replicate the information from server to server, but it seems like that
would start to get somewhat unruly.
