[OpenSER-Users] Failover using NAPTR/SRV

[Tobias Lindgren]

Hi all,

I've been trying to find this information but I cannot find any exact 
specifications on how it really works.

 From what I know using NAPTR/SRV records with OpenSER will allow it to 
find and use servers behind those DNS-records. This works just fine.

However, what I'm not sure about is what actually will happen in OpenSER 
when one of two servers in this scenario would fail.

For example, I have two servers as SRV where one is primary and one is 
secondary for SIP/UDP. What will happend in OpenSER when the primary 
server is down? Will OpenSER continue to send all request first towards 
that server or will it learn that one server is down and always send 
requests to the second server for a period of time and try the primary 
one just occassionally?

Please direct me to any page where this is explained in detail, if such 
page exists.

Br,
/Tobias
