First, if you need to unlock the e173 dongle you can download Huawei_Modem_Unlocker.zip
unzip it, put the dongle in the pc and then check with the mouse unlock button.

aptitude install usb-modeswitch usb-modeswitch-data

Install sqlite3 libssl-dev ncurses-dev libxml2-dev libxml2 libiksemel-dev gcc make subversion

Download the asterisk from the official web site.

wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-1.8-current.tar.gz

tar -zxvf asterisk-1.8-current.tar.gz

cd asterisk-1.8-current

then : make clean && ./configure && make menuselect && make && make install && make samples && make config

Ok the Asterisk is ready, you have to configure the sip.conf and the extension.conf

Next we download the chan_dongle module

wget http://asterisk-chan-dongle.googlecode.com/files/chan_dongle-1.1.r14.tgz

tar -zxvf chan_dongle-1.1.r14

cd chan_dongle-1.1.r14

./configure && make && make install

cp etc/dongle.conf /etc/asterisk/

/etc/init.d/asterisk restart

asterisk -vvvvvr


dongle show devices

Now it works

in extensions.conf

you can put for receiving sms and ussu

[dongle-incoming]
exten => sms,1,Verbose(Incoming SMS from ${CALLERID(num)} ${BASE64_DECODE(${SMS_BASE64})})
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)
