After typing ps aux | grep asterisk I noticed there are five instances of asterisk running

asterisk   4493  0.0  0.6  23720  3540  ?      S    15:12      0:00     /usr/sbin/apache2 -k start
asterisk   4494  0.0  0.6  23720  3540  ?      S    15:12      0:00     /usr/sbin/apache2 -k start
asterisk   4495  0.0  0.6  23720  3540  ?      S    15:12      0:00     /usr/sbin/apache2 -k start
asterisk   4496  0.0  0.6  23720  3540  ?      S    15:12      0:00     /usr/sbin/apache2 -k start
asterisk   4497  0.0  0.6  23720  3540  ?      S    15:12      0:00     /usr/sbin/apache2 -k start
root         4617  0.0  0.1   3004    764  pts/0 R+  15:33      0.00     grep asterisk

After running cat/proc/dahdi/* :  It is all in caps
