pjsip android stun超时

Question

我在android上为pjsip创建了最新的主干，得到了stun错误：

12-10 00:19:25.340  21917-21917/I/pjsua﹕ pjsua version 2.1-svn for Linux-3.0.15/armv7l initialized

12-10 00:19:27.380  21917-21917/I/pjsua﹕ PJSUA state changed: INIT --> CLOSING

同样的stun配置可以在相同的代码下正常工作(在iOS和旧的pjsip干线上)：

my_config->cfg.stun_srv_cnt = 3；

const char *stun = "ip1:3480";
if (stun && strlen(stun)) pj_strdup2_with_null(my_config->pool,&(my_config->cfg.stun_srv[0]),stun);
const char *stun1 = "ip2:3480";
if (stun1 && strlen(stun1)) pj_strdup2_with_null(my_config->pool,&(my_config->cfg.stun_srv[1]),stun1);
const char *stun2 = "ip3:3480";
if (stun2 && strlen(stun2)) pj_strdup2_with_null(my_config->pool,&(my_config->cfg.stun_srv[2]),stun2);

ip1-3是我的ip地址，如1.1.1.1

对我来说有两件事看起来很奇怪: 1.根据日志，stun服务器被找到了ip地址，但由于未知的原因，又开始重新查找。2.为什么pjsip lib不尝试下一台服务器，而只是停止库。

我尝试执行_config->cfg.stun_ignore_failure= PJ_TRUE；但没有成功...
