I think there are some Polycoms that support RFC 3428 SIP MESSAGE for
instant messaging eg. Kirks.

Also how long should it display for, do you want a sound to play, should
it interrupt users currently on a call, present an interface to
acknowledge the message, etc.

Disregarding RFC 3428 method, for SPIP, VVX, and probably a few other
Polycom models, you can push XML to the phones via HTTP using something
like CURL...

Here's some Asterisk dial plan example (but put this all on one line):

exten => s,n,TrySystem(
--max-time 1
"<PolycomIPPhone><URL priority='critical'>hi.php</URL></PolycomIPPhone>"
-u "push_username:push_password"
-H "Content-Type: application/x-com-polycom-spipx"

You'll need to update the IP to match your phone, run a webserver to
host hi.php, and set a few things up in your Polycom configs, such as
push_username and push_password, but hopefully that helps pop you in the
right direction.
