[incoming]
exten => ussd,1,NoCDR
 same => n,System(echo '${STRFTIME(${EPOCH},,%Y-%m-%d %H:%M:%S)} - ${DONGLENAME}: ${BASE64_DECODE(${USSD_BASE64})}' >> /var/log/asterisk/ussd.txt)
 same => n,Hangup

Now this dialplan, but in the CDR one empty record (2st normal record disabled 
NoCDR() application).
