I beg to differ...
Please re-read my statement that "...unless instructed to do
otherwise..."

So you have now instructed the browser, via javascript, to periodically
poll the server "every once in a while".
This is exacly what the previous poster (the one I replied to) was
trying to AVOID, and for good reason. It doesn't scale. In order to be
effective as a way to present the user with caller-ID driven data, it
would have to poll quite frequently.  With a handful of clients
constantly doing this, the impact is inconsequential, but as the number
of clients hammering the server in this manner climbs, things are going
to break.
