在同时设置了 IPV6 和 IPV4 地址的环境中才会出现，测试部门竟然没覆盖到：

void getRelayTuple(bool destinationIsPrivate, 
                       bool destV4,
                       int64_t& serverId,
                       voice::Tuple& relayTuple)
    {
        serverId = mServerId;

        std::string & address4 = destinationIsPrivate ? mPrivateServerIp4 : mPublicServerIp4;
        std::string & address6 = destinationIsPrivate ? mPrivateServerIp6 : mPublicServerIp6;
        if (!address4.empty() || !address6.empty())
        {
            std::string& ipAddress = !address4.empty() ? address4 : address6;
            if (!destV4)
            {
                ipAddress = !address6.empty() ? address6 : address4;
            }

            relayTuple = voice::Tuple(ipAddress, mRelayPort, proto::UDP);
        }
    }
