    Hello.

    I have a Voip provider, which from time to time suffers DDOS attacks. In order to overcome this situation, I want to configure the SRV record to load balancing/failover voip provider.

    The voip provider have two servers:
    • server1.MyVoipProvider.net
    • server2.MyVoipProvider.net
    I add SRV records in my DNS server. Bellow a sample of my SRV record:
    • _sip._udp.MyVoipProvider.net
    and put this record in "SIP server hostaname or IP" field on 3CX Voip provider config.

    But I can't register the line. I got the error:
    • "Cause: 503 Service Unavailable/REGISTER from local"

    Anyone can help me?

    Thank you.

    Best regards.

    Ricardo
