Configuring Advanced Features
125
Parameters are explained in the following table:
Parameter
Description
Priority
Specify preferential treatment for the specific host entry. Lower
priority is MORE preferred.
Weight
When priorities are equal, weight is used to differentiate the
preference. The preference is from highest to lowest. Again,
keep the same to load balance.
Port
Identify the port number to be used.
Target
Identify the actual hosts for an A query.
The two SRV records point to different hosts. The two records have the same priority 0.
The weight of the second record is higher than the first one, so the second record is
picked first. If there is no IP address returned in the response, the IP phone sends out an
A query to look up the IP address. So in this case, the IP phone will use
"server1.example.com" and "server2.example.com" for the A query.
A (Host IP Address)
The IP phone performs an A query for the IP address of the target host name. The
sample of an A record for reference:
IN A 62.10.1.10
The following figure illustrates the IP phone has the availability of performing DNS SRV
query, and fails over the request to the secondary server when there is no response
from the primary server.
Procedure
DNS SRV query can be configured using the configuration files or locally.
Configuration File
<MAC>.cfg
Configure the DNS SRV query
on the IP phone.
