Run Asterisk non-persistently in a Docker container

README

* Put config in /docker/asterisk/config
* Put g723 and g729 codecs in /docker/asterisk/codecs and list in systemd unit startup
* Create /docker/asterisk/logs dir for logs, /docker/asterisk/logs/cdr-csv for call records
* Set udpbindaddr and tcpbindaddr in sip.conf to your secondary IP
* Set rtpstart and rtpend in rtp.conf appropriately
* Add a second IP to your Docker host's main interfaces
* make build
* make install
* make start
* Rejoice!
