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.
