標題: CSL SMS encode/decode [打印本頁]

作者: ttmuskie 時間: 2016-11-9 14:00 標題: CSL SMS encode/decode

I have a USB dongle (with a "Hello" Prepaid Card inserted) attached to my Asterisk server. Everyday, a cron job will run a program to check the balance of the prepaid card. It's been running for over 2 years without any problem.

Today, I got the SMS that seems "encoded" from the CLI:

[dongle0] Got SMS from 179179: '(QKA_ESYKA_A^MAr_keA eKaCSIA&FCeIARgAllpfdpfrX@B]IAhQKAdK[CS]S]OAlCYkKARgAnh\drv@lCYSIAhSYYAdd^C]_d`bn\@ YKCgKAlSgSiAPiiau^^`eKaCSI]PWGgY]F_[AL_eA'

複製代碼

Is there anyone know how to "decode" it?

I used Dongle for standby line and using following config to receive SMS even Chinese is OK. SMS will be email out to mailbox.

[from-trunk-dongle]
exten => sms,1,Noop(Incoming SMS from ${CALLERID(num)} ${BASE64_DECODE(${SMS_BASE64})})
exten => sms,2,System(echo "Subject: SMS received from ${CALLERID(num)}" > /var/log/asterisk/smsmail)
exten => sms,3,System(echo " " >> /var/log/asterisk/smsmail)
exten => sms,4,System(echo '${BASE64_DECODE(${SMS_BASE64})}' >> /var/log/asterisk/smsmail)
exten => sms,5,System(sendmail -f XXXXXX@gmail.com -t XXXXXXX@gmail.com < /var/log/asterisk/smsmail)
exten => sms,n,System(echo '${STRFTIME(${EPOCH},,%Y-%m-%d %H:%M:%S)} - ${DONGLENAME} - ${CALLERID(num)}: ${BASE64_DECODE(${SMS_BASE64})}' >> /var/log/asterisk/sms.txt)
exten => sms,n,Hangup()

我有一个大陆联通沃信号码挂在piaf上，有时候也收到短信，但从来不知道内容，你的这个办法好，但不知道如何用在我的系统上！

安装及配置好 Chan_dongle 再把上面的，贴到 extensions_custom.conf 内，重启 asterisk

各位師兄 , 我重裝了raspbx 新舊版本 , 仍然pccw check balance ##21# 的SMS 無法decode , 也試了edmond25 提供的script , 都不成功 , 我2015年做是沒有問題的 , 請問有沒有什麼資料 ?

==> 後記 , 經再三測試 , 是Pccw 的 ussd ##21# 出亂碼 , 我用其他方法send 中文,日文 sms 都沒有問題 !!

The Mobile No of your Prepaid SIM card is xxxxxxxx, and the remaining value is $48.00; valid till 11/Mar/2018. Please visit http://prepaid.hkcsl.com for data usage enquiry.

btw ##21# 係飛線喎.

BTW, can you share the cronjob script for checking balance?

I'm using python:

#!/usr/bin/python
# -*- coding: utf-8 -*-
import os
cmd = "sudo /usr/sbin/asterisk -rx 'dongle ussd dongle0 ##122#'"
os.system(cmd)

Btw, for the encode/decode problem I've raised last year, it was fixed by itself (it mean I didn't change anything) after a week or so.

Thanks. I had just put it in a shell script and put under the crontab. Are you going to implement some alert if the amount is lower than a specific value? or the expiry date? These are more interesting to look at for automation.

Good suggestion

搵左幾日，原來 decode sms 既 PDU 係咁困難，啲library一係就只做send, 一係就勁難用.
有冇啲library係可以就咁用command line pass 個pdu string 就用到?

唔該晒先 , 亂碼只係出現係用hello SIM send ussd ##122# check balance 時 , 由於我見SMS 無問題 , 我無再理佢了
