To be found you need the correct DNS server configuration. If you
only have one proxy running and you do not plan to use redundancy, all
you need to do is make your host known in this DNS server.
To use the DNS searching support, you need to define entries
for "_sip._udp" and "_sip._tcp" for your domain and assign weights
and probabilities to the different hosts that serve these services. A
configuration file for Linux might look like this:
$TTL 1D
anycom.de. IN SOA
IN NS
IN NS
_sip._tcp.anycom.de.
_sip._udp.anycom.de.
localhost IN A
ns IN A
anycom.de. IN A
test IN A
www IN A
sip-server IN A
In this example, there are three choices for accessing the proxies
for anycom.de. The first two, (sip-server.anycom.de and test.anycom.de)
have the weight 0, and as long as one of them is up they will be contacted.
Only if both of them are down, will the service go to www.anycom.de. The
probability of contacting sip-server is 5/6, the probability of contacting
1/6, as the preference sum is 6. That means that most of the load goes
to sip-server.
