Description
If enabled, the user does not have to be registered with
the proxy to answer calls.
Defaults to no.
Enables DNS SRV lookup for the proxy and outbound
proxy.
Defaults to no.
Enables the phone to automatically prepend the proxy or
outbound proxy name with _sip._udp when performing a
DNS SRV lookup on that name.
Defaults to no.
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 via DNS SRV record lookup on the server
name. It needs to know proxy priority; otherwise, it does
not retry.
Defaults to 3600 seconds.
Select Normal or Based on SRV port. The phone creates
an internal list of proxies returned in the DNS SRV
records.
If you select Normal, the list contains proxies ranked by
weight and priority.
If you select Based on SRV, the phone uses normal, then
inspects the port number based on the first-listed proxy
port.
Defaults to Normal.
