Summary: app_system() sets SYSTEMSTATUS randomly not
dependant on the return result of the linux system call
Description:
System() sets SYSTEMSTATUS to random values of SUCCESS or APPERROR on
sequential tests w/o any other changes to the dialplan or configuration...
the scenario is call screening. in sounds/callerannounce directory, we
store a file containing a .gsm recording. the filename is the
CALLERID(num).gsm. when a call starts we check for the existance of the
file. if the file exists, we connect to the extension. if the file does
not exist, we ask the caller to record his/her name and store it in the
sounds/callscreen directory. we tried the STAT() call and it did not stat
the file correctly so we went for the System() and used the Linux stat
command. the * system() did not fair any better. here is the output of
three sequential tests...
dialplan segment
----------------
;; use the STAT command when the bug is fixed, until then use Linux stat()
w/ * System()
exten => s,n,NoOp(DEBUG: (before) system() set as ${SYSTEMSTATUS})
