When the static DNS cache is used, the sip.cfg configuration would look as

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"

When the static DNS cache is not used, the sip.cfg configuration would look

as follows:

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 sip.cfg 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"
