Proxy Fallback
Intvl
This parameter sets the delay (sec) after which the ATA
will retry from the highest priority proxy (or outbound
proxy) servers after it has failed over to a lower priority
server. This parameter is useful only if the primary and
backup proxy server list is provided to the ATA via DNS
SRV record lookup on the server name. (Using multiple
DNS A record per server name does not allow the notion
of priority and so all hosts will be considered at the same
priority and the ATA will not attempt to fall back after a fail
over).
Default setting: 3600
Proxy Redundancy
Method
The ATA makes an internal list of proxies returned in DNS
SRV records. In normal mode this list will contain proxies
ranked by weight and priority.
If the parameter
Based on SRV port
is configured, the ATA
creates a list in normal mode first, and then inspects the
port numbers based on the 1
st
proxy’s port on the list.
Default setting: Normal
