Postmaster @ (or what are best practice to send SMS these days)

My recommendation as of late has been to use WCTP with a TAP backup. 
(using qpage at $WORK)

This way you get the faster delivery/rate of WCTP, with an OOB fall-back 
should it be needed.

Most pager companies (and presumably many cell providers) provide 
interfaces for one/both of the above.
