[asterisk-dev] AOC in chan_sip

[Ibrar Ahmed]

I think code should look like this

typedef struct
{
    char* charging_info;         /* Chraging information like "currency" */
    char* charging_info_val;   /* Charging information value like 
currency = USD */
    float amount;                     /* Amount to charge */   
    float multiplier;                 /* Multiplier */
}aoc;

/*! \brief Transmit SIP AOC unreliably */
static int transmit_sip_aoc(struct sip_pvt *p)
{
        struct sip_request req;
        char aocs[255]; /* String to hold value of aoc */

        reqprep(&req, p, SIP_INFO, 0, 1);
        add_header(&req, "Content-Type", "application/QSIG");
        snprintf(aocs, sizeof(aocs),
                    "charging;state=active\
                    \n charging-info=%s\
                    \n currency=%s\
                    \n amount=%f\
                    \n 
multiplier=%f",p->aoc.charging_info,p->aoc.charging_info_val,p->aoc.amount,p->aoc.multipier);

        add_header(&req, "AOC",aocs);
        add_header_contentLength(&req, 0);
        return send_request(p, &req, 1, p->ocseq);
}
