Yes, I store the calls timezone in tis variable before the code sample
you got.

I've implemented 5 as a pause-button on the phone. This context handles
this by playing a
prompt that you have pause the recording and <time> and <date>.
This is repeated untill the user presses a key on the keypad.

${filename} is the file you want to play.
60000 is 60 seconds to skip.
3 is to use 3 as forward 60 seconds
1 to to use 1 as rewind 60 seconds
*#2456790 is used as stop buttons (and handled by the dialplan)
o() is a option to go to a specific position in the file
${position} is the variable that hold the current position of the playback.
To get more details use the following command:
asterisk*CLI> core show application ControlPlayback
