Maybe this is old news, but I noticed that Sqlite is used by "OpenPBX," an open source PBX. I would think it's yet another tribute to Sqlite's reliability that it was chosen to run in a phone switch.
--------------------- OpenPBX is a fork of the Asterisk PBX. On the home page of the OpenPBX wiki: http://wiki.openpbx.org/tiki-index.php Under the topic: *Most important differences between OpenPBX and Asterisk* they include: "OpenPBX.org uses Sqlite instead of Berkeley DB as its internal database " [opinions are mine, and not necessarily those of my company]
