Examples
Example 1
This example shows how to configure static DNS cache using A records IP addresses in SIP
server address fields.
When the static DNS cache is not used, the configuration would look as follows:
reg.1.address="1001"
reg.1.server.1.address="172.23.0.140"
reg.1.server.1.port="5075"
reg.1.server.1.transport="UDPOnly"
reg.1.server.2.address="172.23.0.150"
reg.1.server.2.port="5075"
reg.1.server.2.transport="UDPOnly"
When the static DNS cache is used, the configuration would look as follows:
reg.1.address="1001"
reg.1.server.1.address="sipserver.example.com"
reg.1.server.1.port="5075"
reg.1.server.1.transport="UDPOnly"
reg.1.server.2.address=""
reg.1.server.2.port=""
reg.1.server.2.transport=""
dns.cache.A.1.name="sipserver.example.com"
dns.cache.A.1.ttl="3600"
dns.cache.A.1.address="172.23.0.140"
dns.cache.A.2.name="sipserver.example.com"
dns.cache.A.2.ttl="3600"
dns.cache.A.2.address="172.23.0.150"
Parameter order
Above addresses are presented to SIP application in order, for example,
dns.cache.A.1, dns.cache.A.2, and so on.
