Witam! In case of any problems with the STUN server, pjsua returns a relevant error. I think that setting the STUN server/host list in psjua would be a much better and useful idea, just how it is with nameserver or outbound_proxy, the library would be using the next one from the host list, if there's something wrong with the current one, it doesn't respond, it can't connect or sth. Any ideas or suggestions? -- Pozdrowienia, Marcin 'Malcom' Malich me at malcom.pl http://malcom.pl
