Issue: pjsua app: using with dual stack host pjsua --ipv6 does not set pjsua_ipv6_use in the account config; during INVITE the SDP will show IPv4 addresses. Version: pjproject github master Expected behaviour: pjsua ... --ipv6: client can REGISTER and make calls INVITE Observed behaviour: pjsua ...--ipv6 1. REGISTER succeeds (Contact address is indeed IPv6) 2. INVITE fails (SDP shows IPv4 addresses) Cheers Anthony
