说明：
在封装sip协议栈的操作接口时，最好是使用SIP协议栈提供的接口，比如：
使用pj_ansi_snprintf这个函数，而不直接使用C的snprintf或是sprintf函数。
int qt_sip::sip_register(char *cname,char *cpasswd,char *sdomain)
{
pj_status_t status;
/* Register to SIP server by creating SIP account. */
{
pjsua_acc_config cfg;

//local地址
//minisipserver的ip地址：100.100.100.199
//在minisipserver服务器上添加SIP账号，名称：100，密码：100
//形式："sip:账号名称@服务器地址"
pj_ansi_snprintf(uri, PJSIP_MAX_URL_SIZE,
"sip:%s@%s",
cname,sdomain);
cfg.id = pj_str(uri);
//服务器地址
/ /形式：“sip:地址”
//“sip:100.100.100.199”
char reg_uri[PJSIP_MAX_URL_SIZE];
pj_ansi_snprintf(reg_uri, PJSIP_MAX_URL_SIZE,"sip:%s",sdomain);
PJ_LOG(3,(THIS_FILE, "***%s***",reg_uri));
cfg.reg_uri = pj_str(reg_uri);
cfg.cred_count = 1;
char realm_uri[PJSIP_MAX_URL_SIZE];
pj_ansi_snprintf(realm_uri,100,"%s",sdomain);
PJ_LOG(3,(THIS_FILE, "***%s***",realm_uri));
cfg.cred_info[0].realm = pj_str("*");
//cfg.cred_info[0].scheme = pj_str("digest");
cfg.cred_info[0].username = pj_str(cname);
cfg.cred_info[0].data_type = PJSIP_CRED_DATA_PLAIN_PASSWD;
cfg.cred_info[0].data = pj_str(cpasswd);
status = pjsua_acc_add(&cfg, PJ_TRUE, &g_acc_id);
if (status != PJ_SUCCESS)
return -6;
}
return 0;
}
拨号
//在minisipserver服务器上添加SIP账号，名称：101
//使用另外的客户端注册
//拨打101，命令格式：“sip:101@100.100.100.199”
int qt_sip::sip_dial(char *phonenum)
{
pj_status_t status;
char tmp_uri[PJSIP_MAX_URL_SIZE];
pj_ansi_snprintf(tmp_uri, PJSIP_MAX_URL_SIZE,
"sip:%s@%s",
phonenum,g_server_name);
/* If argument is specified, it's got to be a valid SIP URL */
