ussd warning about asterisk-chan-dongle HOT 3 OPEN

Whats write in your dialplan for USSD ?

do not forget Hangup Local channel for incoming USSD and SMS:

[dongle-incoming]
exten => ussd,1,NoOp()
... something else
exten => ussd,n,Hangup

Проблема через кавичку, попробуй так:
 exten => ussd,1,NoOp(Incoming)
 ;exten => ussd,n,Verbose(Incoming USSD: ${BASE64_DECODE(${USSD_BASE64})})
 exten => ussd,n,Set(USSD_MOD=${BASE64_DECODE(${USSD_BASE64})})
 exten => ussd,n,System(echo '${STRFTIME(${EPOCH},,%Y-%m-%d %H:%M:%S)} - ${DONGLENAME}: ${REPLACE(USSD_MOD,\')}' >> /var/log/asterisk/ussd.txt)
 exten => ussd,n,Hangup()
