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: 15:45:50.278 pjsua_core.c Trying STUN server stun.voip.eutelia.it (1 of 1).. ^[[5~ 15:45:50.327 pa_dev.c PortAudio sound library initialized, status=0 15:45:50.327 pa_dev.c PortAudio host api count=1 15:45:50.327 pa_dev.c Sound device count=2 15:45:50.328 pjlib select() I/O Queue created (0x8e0a61c) 15:45:58.181 stuntsx0x8e096 STUN timeout waiting for response 15:45:58.181 stunresolve Session failed because STUN Binding request failed: STUN transaction has timed out (PJNATH_ESTUNTIMEDOUT) 15:45:58.181 pjsua_core.c STUN resolution for stun.voip.eutelia.it failed: STUN transaction has timed out (PJNATH_ESTUNTIMEDOUT) 15:45:58.181 pjsua_core.c STUN resolution failed: STUN transaction has timed out (PJNATH_ESTUNTIMEDOUT) 15:45:58.199 pjsua_core.c Ignoring STUN resolution failure (by setting) thank you Giorge Alice Messenger ;-) chatti anche con gli amici di Windows Live Messenger e tutti i telefonini TIM!
