I think load-balancing was introduced in version 2.0, so there is no way
to configure it in 0.9.x.
In 2.x, you need to enable it explicitly:
dns_srv_lb=1

Hello list users,
i want to use ser as a load balancing proxy for some PSTN
gateways that I have in use.
My idea is to use the rewritehost() core function and DNS SRV
entries to accomplish this. But it seems that ser is doing a
A record lookup if I simply replace the host with my domain
"mynet.interx":
if ( ... ) {
rewritehost("mynet.interx");
t_relay();
}
Ser is running on the same host (89.49.16.54) as the authorative
nameserver for the mynet.interx domain.
dig shows that the DNS files are configured in the right way for
load balancing, but I just can't find a way to make ser as a dns client
work like dig.
If I use "_sip._udp.mynet.interx" it will complain about a bad name.
Well he is partly right, underscores are not allowed in domain names.
And if I use only the domain in the rewrite command it will contact
the IP of the nameserver of this domain. Or in other words it will send
the messages to itself.
Using directly rewritehost("sip1.mynet.interx") doesn't help me,
because it wouldn't do load balancing.
How can I convince ser (version 0.9.6) to use the correct lookup
method for the DNS?
Any hints are appreciated ...
Thanks, Rolf.
