Why is the call not being recorded?

Question

Asterisk

Good afternoon.

Can you please tell me why the call is not being recorded?
Asterisk 13.1.0

Created dialplan
;TEST EXTEN
exten => 999,1,SET(fname=${UNIQUEID})
same => n,Monitor(wav,/home/rec/${fname},mb)
same => n,Answer()
same => n,Wait(5)
same => n,Playback(beep)
same => n,Wait(2) same => n ,
Hangup()

home/rec, no record file is created in /var/spool/asterisk/monitor. What have I done wrong?

Answer 1

chmod 0777 /home/rec
If he writes, then deal with the rights of the directory
I assume that the asterisk is built with wav support ???
