Solved Configure SRV record to load balancing/failover voip provider

[ricardolobo]

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
