Just so ppl you're asking don't lose their minds either trying to be clairvoyants of your particular setup, can you post what records exactly were added and what makes you think they are not followed by Kam when selecting a destination?

So you add records with dns.add and then lookup them up with dns.lookup

Hello,

 

Just to be sure that I'm not losing my time: is there any chance to do a load-balancing using add_srv? I just tried with two equal entries but it's always the same which is returned.

 

Regards,

 

Igor.

Hello,

the core rpc lack proper documentation, not like the case of modules. In this case, the code should be suggestive of what parameters have to be provided:

  - https://github.com/kamailio/kamailio/blob/master/src/core/dns_cache.c#L4744

For each of those values, the corex docs for dns_cache parameter should give details.

Cheers,
Daniel

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
