[pjsip] stun problem help request

[giorge27 at alice.it]

I don't understand the reason that d0nt' abilitate STUN server

I use this code in python pjsip:
			userAgentCfg = pj.UAConfig()
			userAgentCfg.stun_host = "stun.voip.eutelia.it"
			lib.init(ua_cfg=userAgentCfg, log_cfg = pj.LogConfig(level=LOG_LEVEL,  callback=self.call_backLog))


and i've always as result the stun server not abilitated and those logs:


log_cb:  15:37:52.585   pjsua_core.c  STUN resolution failed: STUN transaction has timed out (PJNATH_ESTUNTIMEDOUT)
log_cb:  15:37:52.597   pjsua_core.c  Ignoring STUN resolution failure (by setting)
log_cb:  15:37:52.597   pjsua_core.c  pjsua version 1.4 for i686-pc-linux-gnu initialized
 
i've tried even "pjsua" client with the option "--stun-srv=stun.voip.eutelia.it" and i've  the same behavior.
In this case the log are:
