Hi, I'm wondering how to configure DNS for working with pjsip SRV resolution properly. Now I have something like this: Domain for VoIP: sip.domain.com Two SRV serviecies: _sip._udp.sip.domain.com SRV service location: priority = 1 weight = 0 port = 5060 svr hostname = sip1.domain.com _sip._udp.sip.domain.com SRV service location: priority = 0 weight = 0 port = 5060 svr hostname = sip2.domain.com and two type A records: sip1.domain.com internet address = SOME_ADDRESS sip2.domain.com internet address = SOME_ADDRESS2 When starting pjsua 1.12 with --nameserver=sip.domain.com argument it ends up with this error: pjsua_core.c Error setting nameserver: Invalid DNS nameserver a ddress (PJLIB_UTIL_EDNSINNSADDR) [status=320044] Kindly let me know any clues. Best regards, Coopara
