Hi Pierre-Luc Bacon, The IP of VMwareWorkstation is 10.10.10.1, and it cannot access the NGN Server. My PJSIP version is pjproject-1.1. Now I found in method create_sip_udp_sock in pjsua_core.c, pjsip should Get the published address, either by STUN or by resolving the name of local host. Before calling method pj_gethostip, I print out the value in p_pub_addr, the IP is 0.0.0.0, after calling, the value is 10.10.10.1. So I think the method pj_gethostip is the primary point. pj_gethostip call method pj_getaddrinfo to get all IP addresses. But I do not find the Detecting the default route? Exactly it did call pj_enum_ip_interface -> enum_ipv4_interface to enumerating IP interfaces and use the first one. So my question is: 1. Where is it to detecting the default route 2. How can I determine the appropriate IP interface if there is route for every IP interface? Should I ping the destination IP first? 2009/8/11 Pierre-Luc Bacon <pierre-luc.bacon at savoirfairelinux.com> > I'm not sure I'd call that a bug.
