Account/Network Settings 
This  parameter  controls  how  the  Search  Appliance  looks  up  IP addresses  for 
hostnames. There are four modes: A Record, SRV, NATPTR/SRV, Use Configured 
IP. The default setting is “A Record”. If the user wishes to locate the server by DNS 
SRV, the user may select “SRV” or “NATPTR/SRV”. 
 
If “Use Configured IP” is selected, please fill in the three fields below: 
-  Primary IP: 
-  Backup IP 1. 
-  Backup IP 2. 
If SIP server is configured as domain name, phone will not send DNS query, but 
use “Primary IP” or “Backup IP x” to send SIP message if at least one of them are 
not empty. 
Phone will try to use “Primary IP” first. After 3 tries without any response, it will 
switch to “Backup IP x”, and then it will switch back to “Primary IP” after 3 re-tries. 
If  SIP  server  is  already  an  IP  address,  phone  will  use  it  directly  even  “User 
Configured IP” is selected 
The option will decide which IP is going to be used in sending SIP packets after 
IPs for SIP server host are resolved with DNS SRV. 
-    Default 
If the option is set with “default”, it will again try to send register messages to one 
IP at a time, and the process repeats. 
-  Saved one until DNS TTL 
If the option is set with “Saved one until DNS TTL”, it will send register messages 
to the previously registered IP first. If no response, it will try to send one at a time 
for each IP. This behavior lasts if DNS TTL (time-to-live) is up. 
-  Saved one until no responses 
If  the  option  is  set  with  “Saved  one  until  no  responses”,  it  will  send  register 
messages to the previously registered IP first, but this behavior will persist until the 
registered server does not respond.
