Announce current time as part of call flow

In the file extensions_custom.conf add the lines:

[read-current-time]
exten => s,1,Noop(Entering user defined context read-current-time in extensions_custom.conf)
exten => s,n,Answer
exten => s,n,SayUnixTime(${FutureTime},,IMp)    ; modify the options to suit how you want time read back
exten => s,n,return

In Admin, custom Destinations, create a new destination with a target of read-current-time,s,1, enable ‘Return’ and set the caller destination. Then send the caller to this custom destination after your announcement.
