Despite what anyone may say about Fax over IP allegedly works for them,
save yourself the trouble and make sure you take the POTS and ISDN
approach.

Most major phone vendors offer provisioning of this nature.

Polycom supports this, and I am quite sure Snom does too.  Perhaps some
others.

As far as how to implement it, that is manufacturer-specific.  Look on
voip-info.org for "Polycom" and "paging" if you want the
Polycom-centric
answer.  For other phones, it will be different.
