[OpenSIPS-Users] Pre-load different routes after DNS NAPTR/SRV lookup

[Bogdan-Andrei Iancu]

Hello,

OpenSIPS automatically does DNS-based failover (using the NATPR, SRV and 
A records for the domain) - there is not need to do it manually from 
script. Using the same principal (serial forking), transparent for you, 
OpenSIPS TM module will do it for you.

See the "disable_dns_failover" param -
