Am I wrong in thinking that the idea behind SNPP is that you *wouldn't* need to use a modem to dial out to make pager requests, and that they would be sent through the internet?
SNPP is a client-server protocol that is separate from the actual mechanism used to deliver the page requests. If you can find a service provider that honors SNPP and is accessible directly through the internet then no phone calls are needed. HylaFAX can act as a gateway between SNPP clients and providers that talk IXO/TAP (or other protocols) so SNPP-capable clients can utilize services now while there are still few SNPP-capable service providers. There are however limitations in this gateway capability caused by IXO/TAP being a 1-way protocol (so, for example, it's not possible to do some things based on a pager's capabilities). It is possible to add more extensive per-pager database information to simulate what a pager service provider knows but I didn't think it was worthwhile (but if many folks make use of the pager facilities then maybe someone will extend/improve stuff along those lines).
