How to remove first 3 digits/letters from CALLED NUMBER. Let's say number 123456789 calls to abc987654321. I want to remove abc because in the context I have only 987654321. I know how to cut from CALLER but don't know how to cut from CALLED(Destination) number. This is what I tried so far but nothing happen:

exten => _[a-z]XXXXXXXXXXXX,1,Set({CALLEDID}=${CALLEDID:3})
exten => _[a-z]XXXXXXXXXXXX,2,Dial(SIP/${CALLEDID},1)
exten => _[a-z]XXXXXXXXXXXX,3,Voicemail(${CALLEDID}@VoiceMail)
exten => _[a-z]XXXXXXXXXXXX,4,Playback(Goodbye)
exten => _[a-z]XXXXXXXXXXXX,5,Hangup

You can use FILTER function or just do goto. You not need cut from destination,you need cut from extension.

exten => _[a-z]XXXXXXXXXXXX,1,Goto(${EXTEN:3},1)

exten => _XXXXXXXXXXXX,1,Dial(SIP/${EXTEN},1)
exten => _XXXXXXXXXXXX,n,Voicemail(${EXTEN}@VoiceMail)
exten => _XXXXXXXXXXXX,n,Playback(Goodbye)
exten => _XXXXXXXXXXXX,n,Hangup

Please note, your dialplan still do voicemail if called part hanguped after call. Read default extensions.conf.sample to see how to deal with voicemail
