[asterisk-users] Asterisk dialplan date and time operations

[Erik Wartusch]

Thanks!

I got it now!

Here is a sample for a delayed callback after a caller gets to a users 
voicemailbox. Purpose: Reminder for people that they got a message on their 
v. box.

 exten => 1002,1,Answer
        exten => 1002,2,Set(CHANNEL(musicclass)=default)
        exten => 1002,3,Queue(test|t|||5)
        exten => 1002,4,Voicemail(b1205)
        exten => 1002,5,System(echo -e "Channel: SIP/we-static\\nCallerID: 
VOICEMAIL
 <8500>\\nContext: test\\nExtension: 444" > /tmp/${UNIQUEID}.call)
 ; add 15 minutes (in seconds 900) to the epoch time
        exten => 1002,6,Set(newepoch=${MATH(${EPOCH} + 900 |int)})
 ; write it out for debugging purpose
        exten => 1002,7,NoOp(${newepoch})
        exten => 1002,8,System(touch -t ${STRFTIME(${newepoch},,
%Y%m%d%H%M)} /tmp/${
UNIQUEID}.call)
        exten => 
1002,9,System(mv /tmp/${UNIQUEID}.call /var/spool/asterisk/outgoing
/)
        exten => 1002,10,Hangup


Kind Regards,

Erik
