File Issue with Call Recording

Update 2

Found this post

and changed

/etc/asterisk/extensions_custom.conf

to

[Lenny]
exten => talk,1,Set(i=${IF($[“0${i}”=“016”]?7:$[0${i}+1])})
same => n,ExecIf($[${i}=1]?MixMonitor(${STRFTIME(${EPOCH},%Y/%m/%d)}/itslenny-${CALLERID(dnid)}-${CALLERID(num)}-${STRFTIME(${EPOCH},%Y%m%d-%H%M%S)}-${UNIQUEID}.wav)

same => n,Playback(Lenny/Lenny${i})
same => n,BackgroundDetect(Lenny/backgroundnoise,1500)

It is working the way I want it to now.
