Hello!

 

I have a quick question about the internal DNS resolver and cache embedded in Kamailio.

Is the ability to add an entry with dns.add_a bypass the "real" DNS lookup? So, let's say that sip.example.com is publicly resolve alternatively with 1.2.3.4 & 5.6.7.8.9, if I do a dns.add_a to add my own sip.example.com with, alternatively, 127.0.0.1 and 127.0.0.2, will it work?

yes, it should work, the internal cache is checked first and if entry found, then it is used.

You can also add entries in the dns cache at startup via dns_cache modparam from corex.

Cheers,
Daniel
