Hi
I was configure two stun servers as well:
my_config->cfg.stun_ignore_failure = PJ_FALSE;
my_config->cfg.stun_srv_cnt = 2;
my_config->cfg.stun_srv[0] = pj_str("xx.xx.xx.xx:3480");
my_config->cfg.stun_srv[1] = pj_str("yy.yy.yy.yy:3480");
But sometimes (maybe it depends from connection quantity) i got transport creation error:

Some questions:
- why library told that no response, i seen it in logs
- why transport creation fail without try to next stun server as well.
Changes in stun_simple_client.c do not effect:
enum { MAX_REQUEST = 20 };
static int stun_timer[] = {1000, 1000, 1000, 1000 };
#define STUN_MAGIC 0x2112A442
Changes in my_config->cfg.stun_ignore_failure = PJ_TRUE;
do not effect too
Any ideas? it happened only under macos build, iphone android working well.
