Summary:                    CUT() won't let you cut on a carriage return
Description: 
I'm trying to read in a file into the dialplan, and then parse each line of
the file with the CUT() function, but unfortunately have been unable to
make it work.

I've tried:

Set(LINE=${CUT(ENVELOPE,\n,1)})
Set(LINE=${CUT(ENVELOPE,\\n,1)})
Set(LINE=${CUT(ENVELOPE,\\\n,1)})
Set(LINE=${CUT(ENVELOPE,\r\n,1)})
Set(LINE=${CUT(ENVELOPE,\\r\\n,1)})
Set(LINE=${CUT(ENVELOPE,\\\r\\\n,1)})

But it seems it just cut on the literal letter ('r' or 'n' in this case).

FYI for anyone else who comes across this in the meantime, I've developed a
work around:

exten => 8,n,Set(DATA=${SHELL(tr "\\\n"\, "&" <
${PATH_TO_VM}/${VM_CTX}/${MAILBOX}/INBOX/msg${MSGNUM}.txt \| cut -d \\\& -f
${LINE_NUMBER})})
