Under Subscriber Information,
configure the following fields:
Proxy Fallback Intvl
Sets the delay after which the phone retries from
the highest priority proxy (or outbound proxy) after
it has failed over to a lower priority server.
The phone should have the primary and backup
proxy server list from a DNS SRV record lookup on
the server name. It needs to know the proxy
priority; otherwise, it does not retry.
The range is from 0 to 65535. Defaults to 3600
seconds.
Proxy Redundancy
Method
The phone creates an internal list of proxies
returned in the DNS SRV records.
Select
Normal
to create a list that contains proxies
ranked by weight and priority.
Select
Based on SRV
and the phone creates a
Normal list, then inspects the port numbers based
on the first-listed proxy port. When the weight and
priority match, the device selects the first port in
the list. Defaults to Normal.
