Asterisk is a software implementation of a telephone private branch exchange (PBX); it allows attached telephones to make calls to one another, and to connect to other telephone services, such as the public switched telephone network (PSTN) and (VoIP) services. Its name comes from the asterisk symbol, *.
Asterisk is released with a dual license model, using the GNU General Public License (GPL) as a free software license and a proprietary software license to permit licensees to distribute proprietary, unpublished system components.
Asterisk was created in 1999 by Mark Spencer of Digium. Originally designed for Linux, Asterisk runs on a variety of operating systems, including NetBSD, OpenBSD, FreeBSD, macOS, and Solaris. Asterisk is small enough to run in an embedded environment such as Customer-premises equipment-hardware running OpenWrt. There are complete self-contained versions that can boot from a storage device such as a flash drive or external disk drive (preferably IDE/PATA, SATA or mSATA; a USB-connected device can be used, but is often not recommended). A live CD or virtual machine can also be used.
