Hello;
    There is a problem in acc_radius module that radius message has 2 time sends "Acct-Status-Type = Start" when call is established as example below. it should be ALIVE as i see in rad_status.if req_METHOD is ACK , it should be ALIVE. And There is a problem Sip-Method Problem that even if it is ACK , it sends Invite. How can i fix these problems could you help me about it?
i already defined Acct-Status-Ttpe Values like Below
VALUE Acct-Status-Type   Failed           15   # RFC2866, acc
VALUE Acct-Status-Type   Start            1   # RFC2866, acc
VALUE Acct-Status-Type   Stop             2   # RFC2866, acc
VALUE Acct-Status-Type   Alive           3   # RFC2866, acc

When i debug tag.len in Invite and ack transaction i get 0 value but in Bye it has bigger than 0 .So that it never be Alive

static inline uint32_t rad_status( struct sip_msg *req, int code )
{
        str tag;
        unsigned int in_dialog_req = 0;

        tag = get_to(req)->tag_value;
        if(tag.s!=0 && tag.len!=0)
                in_dialog_req = 1;

        if (req->REQ_METHOD==METHOD_INVITE && in_dialog_req == 0
                    && code>=200 && code<300)
                return rd_vals[RV_STATUS_START].v;
        if ((req->REQ_METHOD==METHOD_BYE || req->REQ_METHOD==METHOD_CANCEL))
                return rd_vals[RV_STATUS_STOP].v;
        if (in_dialog_req != 0)
                return rd_vals[RV_STATUS_ALIVE].v;
        return rd_vals[RV_STATUS_FAILED].v;
 }
