tls pjsua app 分析 pjsua(7)

上面的 ua_cfg 结构体用来参考，后面就分析pjsua_config_default,最后初始化了pjsua_config 参数都是默认值

PJ_DEF(void) pjsua_config_default(pjsua_config *cfg){
    pj_bzero(cfg, sizeof(*cfg));

    cfg->max_calls = ((PJSUA_MAX_CALLS) < 4) ? (PJSUA_MAX_CALLS) : 4;
    cfg->thread_cnt = 1;
    cfg->nat_type_in_sdp = 1;
    cfg->stun_ignore_failure = PJ_TRUE;
    cfg->force_lr = PJ_TRUE;
    cfg->enable_unsolicited_mwi = PJ_TRUE;
    cfg->use_srtp = PJSUA_DEFAULT_USE_SRTP;
    cfg->srtp_secure_signaling = PJSUA_DEFAULT_SRTP_SECURE_SIGNALING;
    cfg->hangup_forked_call = PJ_TRUE;
    cfg->use_timer = PJSUA_SIP_TIMER_OPTIONAL;
    pjsip_timer_setting_default(&cfg->timer_setting);
}

这里又用到了timer_setting 结构体，展示如下

typedef struct pjsip_timer_setting{
    unsigned min_se;//minimum session expiration period >=90 默认是90
    unsigned             sess_expires;  //session expiration period 默认1800
} pjsip_timer_setting;

//最后就是设置时间
PJ_DEF(pj_status_t) pjsip_timer_setting_default(pjsip_timer_setting *setting){
    pj_bzero(setting, sizeof(pjsip_timer_setting));
    setting->sess_expires = PJSIP_SESS_TIMER_DEF_SE;//1800
    setting->min_se = ABS_MIN_SE;//90
    return PJ_SUCCESS;
}

以上就是数据初始化 data init ,然后就是设置默认的log设置

typedef struct pjsua_logging_config{
    pj_bool_t   msg_logging;//Log incoming and outgoing SIP message
    unsigned    level; //输出等级 5
    unsigned    console_level;// 控制台输出 4
    unsigned    decor;
    pj_str_t    log_filename;
    unsigned    log_file_flags;
    void       (*cb)(int level, const char *data, int len);
} pjsua_logging_config;
