so while playing around with call files, one of the most obvious (although unused) applications is probably wake up calls!
wether you want it or now here it is:
exten => s,1,Answer()
exten => s,n,Wait(1)
exten => s,n,Set(year=${STRFTIME(${EPOCH},,%Y)})
exten => s,n,Set(month=${STRFTIME(${EPOCH},,%m)})
exten => s,n,Read(day,date,2,,,8)
exten => s,n,Read(hours,hour,2,,,8)
exten => s,n,Read(minutes,minute,2,,,8)
exten => s,n,NoOp(Wake-up call scheduled for ${CALLERID(num)} at ${hours}:${minutes} on ${day}.${month}.${year}.)
exten => s,n,System(echo -e "Channel: SIP/VoIP-Innovations/${CALLERID(num)}\\nCallerID: "WakeUpCalls.com" <12345678910>\\nApplication: Macro\\nData: wake-up-msg" > /tmp/${UNIQUEID}.call)
exten => s,n,System(touch -t ${year}${month}${day}${hours}${minutes} /tmp/${UNIQUEID}.call)
exten => s,n,System(mv /tmp/${UNIQUEID}.call /var/spool/asterisk/outgoing/)
exten => s,n,Playback(wakeup-call)
exten => s,n,Playback(set)
exten => s,n,Playback(for)
exten => s,n,SayNumber(${hours})
exten => s,n,SayNumber(${minutes})
exten => s,n,Hangup()
then when it calls you back (at the same # you called from)
exten => s,1,Answer
exten => s,n,Wait(1)
exten => s,n,Playback(this)
exten => s,n,Playback(is)
exten => s,n,Playback(your)
exten => s,n,Playback(wakeup-call)
exten => s,n,Wait(1)
exten => s,n,Hangup
of course the above could just be replaced with a "Playback" of some custom greeting instead
when you activate the feature code it asks you for the date of the month (since i have it assume you want the call during the year and month you started, although if it is the last day of the month when you want to put in a wake up for the next day, then that sucks) the hour, and the minute at which time you wish to recieve your wake up call, then
also, i don't believe all of these recordings come with thirdlane, although they do come with asterisk...
