My resolv.conf says: domain yyy.com search yyy.com nameserver 10.10.0.1 When using pj_gethostbyname, server names within the yyy.com domain work fine - I can specify an account id of either sip:123 at pbx or sip:123 at pbx.xxx.com, and pjsip will correctly register. However, after I enable the asynchronous resolver (to get DNS SRV support) by setting nameserver/nameserver_count in pjsua_config, sip:123 at pbx no longer works, because there's no way to specify "search yyy.com" through the api. I'm running 1.12. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/attachments/20120306/cc72f604/attachment.html>
