Call connects with delay

Hi all,

My system (Asterisk 13) was running fine. And the suddenly i started facing this issue. When caller dials a number, it lands on the callee phone with much delay. However when caller dials it again, it connects fine. Issue is when caller dials a new number, issue re-appears. Can anybody tell me where the issue lies?

Slow DNS server. One of two DNS servers not responding. Otherwise you need to provide detailed logs to establish at exactly what point in the call the delay happens.

Dear David,

DNS server problem. The DNS server is not responding, or too many responses are being lost.
