    OpenVox G400P can be implemented to send or receive sms. I will introduce few possible ways to get the features work.
    1) To receive the sms, there is a patch to get sms and store that in text format under asterisk logs,
    customers can use script to parse that and save to somewhere. please refer this link: ... a=page%3D1
    2) To send sms, there are few things users have to consider:
    2.1) the generation of content of sms, users have to store sms in a file.
    2.2) the ways to send sms, from GUI or by dialplan.
    here, i use dialplan to send sms. before starting the configurations, users have to go though:
    1) perl and asterisk::AGI are installed. users have to download the asteriskAGI module.
    asterisk-perl-1.01.tar.gz , unzip that and follow the readme.text to install that.
    2) Make sure G400P is working, edit the dialplan in this way:
    CONSOLE=Console/dsp ; Console interface for demo
    IAXINFO=guest ; IAXtel username/password
    TRUNK=Zap/G2 ; Trunk interface
    sms_test="Test OpenVox G400P by james.zhu" ; default sms, users also can read the file using asterisk cmd and pass the value to the variable.
    exten =>s,1,Answer()
    exten =>s,n,Dial(sip/500)
    exten =>1000,1,Dial(zap/1/10000)
    exten =>1000,2,Hangup()
    exten =>200,1,Dial(zap/3/10000)
    exten =>200,2,Hangup()
    exten =>300,1,Dial(zap/5/10000)
    exten =>300,2,Hangup()
    exten =>400,1,Dial(zap/7/10000)
    exten =>400,2,Hangup()
    exten => _135.,1,AGI(gsm_sms.agi|${EXTEN}|${sms_test})
    exten => _135.,n,hangup
    in this dialplan, if users dial 13570XXXXXX, the agi will be executed and pass to values(${EXTEN}|${sms_test} to gsm_sms.agi. the gsm_sms.agi file must be stored into
    /var/lib/asterisk/agi-bin, and make sure it is executable with asterisk permission.
    this is the sample file called: gsm_sms.agi:
    # Simple AGI Application to show how to send sms by using OpenVox G400P
    # Written by: James.zhu <>
    # Date:12/10/2009
    # include Asteisk AGI, install it first
    use Asterisk::AGI;
    $AGI = new Asterisk::AGI;
    # default channel, use it send sms
    my $channel = 3;
    # the handphone number user dialed
    $number = $ARGV[0];
    # the sms user wants to send
    $context = $ARGV[1];
    # the command line to send sms by asterisk
    # asterisk -rx 'gsm send sms 3 1357080XXXX "hello, this is openvox gsm card"'
    #print "asterisk -rx 'gsm send sms' $channel $number $context";
    # Perl system call
    system("asterisk -rx 'gsm send sms $channel $number $context'");
    please take a note there, i am testing with span 3, please modify that for your needs.

    GSM 3: SMS sent successfully on span 2.
    other possible solutions to send sms using G400P:
    1) use asterisk cli system command: asterisk -rx 'gsm send sms 3 1357080XXXX "hello, this is openvox gsm card"'
    2) save the command above into the bash file, run the system command to launch the sms.
    3) send sms from GUI(PHP, i do not test that), users can login the GUI and fill in a form, which contains message and the phone numbers users want to send to, after submitting, the php file will transfer the context to a bash file. the system will be executed and send that through asterisk -rx command.

    here, i give users an example of using dialplan to send SMS with few static variables. i believe it should be very possible to send sms from GUI, system commands or other solutions.
