I agree with Daniel here. Within the platforms we rarely use DNS as most systems are
fixed
(not moving around, have a permanent IP address) and we handle failover and load
balancing
using solutions like the Kamailio dispatcher.
From the client side, like softphones or desktop phones, I personally use a lot of DNS
to find the first hop SIP server. This way I can manage the clients, control load
balancing,
provider failover and make sure they always reach the service.

Hello,
DNS-based routing is not very common in telecommunications, most of the
interconnects being done based on IP routing and IP-trusted rules.
Because DNS is usually a blocking operation that involves network
communication (therefore can introduce delays), many of the dns features
are turned off by default. When one has to build a system that relies
significantly on DNS-based routing, those features can be turned on via
config.
Cheers,
Daniel

Hi,
I would like to know the reason for having "off" as default value for
use_dns_failover.
