DNS Query ( Circular Method)
TB30 has done an improvement on the mechanism of the DNS Query, which
increases the efficiency on the DNS request.
A new parameter “DNSFB” is introduced and found in Common and MAC
configuration files.
If the value of the parameter is 0, the phone always queries to the Pri DNS
server.
While, if the value of the parameter is 1, DNS query will be using a circular
method, which the phone always starts with the DNS that has provided the
answer to the previous request. If the DNS fails, then try the other and if the
other answers, then use the other in subsequent requests until this one fails.
and so on.
The parameter is configurable via APS and Telnet.
