Additional feature for USSD

[kosfango]

Hi guys,

I propose add next feature (I saw this in the Internet), example:

extension => ussd,1,DongleSendUSSD(dongle0,*100#)
or

[incoming] 
exten => ussd,1,System(/bin/echo '"${STRFTIME(${EPOCH},,%Y-%m-%d %H:%M:%S)} ${USSD}"'|/usr/bin/mail -s "Balance ${STRFTIME(${EPOCH},,%Y-%m-%d %H:%M:%S)}" [email protected]) 

[office] 
exten => _999,1,DongleSendUSSD(dongle0,*100#)

It required:

Add function to app.c:

static int app_send_ussd_exec (attribute_unused struct ast_channel* channel, const char* data) 
{ 
        char*   parse; 
        const char* msg; 
        int status; 
        void * msgid; 

        AST_DECLARE_APP_ARGS (args, 
                AST_APP_ARG (device); 
                AST_APP_ARG (ussd); 
        ); 

        if (ast_strlen_zero (data)) 
        { 
                return -1; 
        } 

        parse = ast_strdupa (data); 

        AST_STANDARD_APP_ARGS (args, parse); 

        if (ast_strlen_zero (args.device)) 
        { 
                ast_log (LOG_ERROR, "NULL device for ussd -- USSD will not be sent\n"); 
                return -1; 
        } 

        if (ast_strlen_zero (args.ussd)) 
        { 
                ast_log (LOG_ERROR, "NULL ussd command -- USSD will not be sent\n"); 
                return -1; 
        } 

        msg = send_ussd(args.device, args.ussd, &status, &msgid); 
        if(!status) 
                ast_log (LOG_ERROR, "[%s] %s with id %p\n", args.device, msg, msgid); 
        return !status; 
}

Next thing needed add to massive [dca]:

{ 
        "DongleSendUSSD", 
        app_send_ussd_exec, 
        "DongleSendUSSD(Device,USSD)", 
        "DongleSendUSSD(Device,USSD)\n"
        "  Device   - Id of device from dongle.conf\n"
        "  USSD     - ussd command\n"
}
