Example 2
This example shows how to configure static DNS cache where your DNS provides A records for
server.X.address but not SRV. In this case, the static DNS cache on the handset provides
SRV records. For more information, go to http://tools.ietf.org/html/rfc3263 .
When the static DNS cache is not used, the configuration would look as follows:
reg.1.address="1002@sipserver.example.com"
reg.1.server.1.address="primary.sipserver.example.com"
reg.1.server.1.port="5075"
reg.1.server.1.transport="UDPOnly"
reg.1.server.2.address="secondary.sipserver.example.com"
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="1002"
reg.1.server.1.address="sipserver.example.com"
reg.1.server.1.port=""
reg.1.server.1.transport="UDPOnly"
reg.1.server.2.address=""
reg.1.server.2.port=""
reg.1.server.2.transport=""
dns.cache.SRV.1.name="_sip._udp.sipserver.example.com "
dns.cache.SRV.1.ttl= "3600"
dns.cache.SRV.1.priority="1"
dns.cache.SRV.1.weight="1"
dns.cache.SRV.1.port="5075"
dns.cache.SRV.1.target="primary.sipserver.example.com"
dns.cache.SRV.2.name="_sip._udp.sipserver.example.com "
dns.cache.SRV.2.ttl= "3600"
dns.cache.SRV.2.priority="2"
dns.cache.SRV.2.weight="1"
dns.cache.SRV.2.port="5075"
dns.cache.SRV.2.target="secondary.sipserver.example.com
Reason for Null setting
The reg.1.server.1.port and reg.1.server.2.port values in this example are set to
null to force SRV lookups.
Example 3
This example shows how to configure static DNS cache where your DNS provides NAPTR and
SRV records for server.X.address .
When the static DNS cache is not used, the configuration would look as follows:
