Description=Asterisk - HTTP server for the directory of the phones

Requires=var-lib-virtiofs-data.mount

# Static files only, operator-provided on the precious-data mount, like the
# TFTP root and for the same reasons. A separate directory from the TFTP root:
# the configuration files of the phones hold their SIP passwords, and HTTP,
# unlike TFTP, is easily reached from another network.

# Start/stop this unit when the target is started/stopped
