QuickPage sends messages to a paging terminal using the SNPP and IXO
(also known as TAP) protocols.  It is normally used with no options
other than a recipient and the message text, in which case the message
is sent to the SNPP server where it is submitted to a page queue to be
sent by a separate daemon process.  Page groups and duty schedules are
supported.  Status notification messages indicating the success or
failure of a page are sent via e-mail to submitters of high-priority
(level 0) pages.

Quickpage can act as an SNPP server or client. For more details on
SNPP, see RFC 1861.
