Description
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.
Set to Yes to enable the Dual registration/Fast Fallback feature. To
enable the feature you must also configure the alternate proxy/alternate
outbound proxy fields in the Proxy and Registration section.
Description

Extension number for this line.
Password for this line. Defaults to blank (no password required).
Authentication ID for SIP authentication. Defaults to blank.
The IP address for an authentication realm other than the proxy IP address.
The default value is blank; the proxy IP address is used as the authentication
realm.
