*installing the common components from the repo currently works and provides a base Asterisk server which will need to be manually configured and started (yum install asterisk asterisk-alsa asterisk-voicemail asterisk-voicemail-plain)

*the asterisk-sounds package required for the echo test and voicemail may not be available due to licensing questions, but should be available from other sources or the Asterisk website as source to be unpacked into the proper directory (/usr/share/asterisk/sounds).
