Proxy.
Default setting: no
DNS SRV Auto
Prefix
If enabled, the ATA will automatically prepend the Proxy or
Outbound Proxy name with _sip._udp when performing a
DNS SRV lookup on that name.
Default setting: no
Proxy Fallback
Intvl
After failing over to a lower priority server, the ATA waits
for the specified Proxy Fallback Interval, in seconds,
before retrying the highest priority proxy (or outbound
proxy) servers. 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 records per server name does not allow
the notion of priority, so all hosts will be considered at the
same priority and the ATA will not attempt to fall back after
a failover.)
Default setting: 3600
Proxy Redundancy
Method
The method that the ATA uses to create a list of proxies
returned in the DNS SRV records. If you select Normal, the
list will contain proxies ranked by weight and priority. If
you select Based on SRV port, the ATA also inspects the
port number based on 1st proxy’s port.
Default setting: Normal
Mailbox Subscribe
URL
