User's Manual
Enables the use of the proxy server's IP address (in dotted-
decimal notation) as the host name in SIP From and To headers
in REGISTER requests.

[0] Disable (default)

[1] Enable
If the parameter is disabled and the device registers to an IP
Group (i.e., proxy server), it uses the string configured by the
ProxyName parameter as the host name in the REGISTER's
Request-URI and uses the string configured by the IP Groups
table parameter, SIPGroupName as the host name in the To and
From headers. If the IP Group is configured with a Proxy Set that
has multiple IP addresses, all the REGISTER messages sent to
these proxies are sent with the same host name.
Note: If the parameter is disabled and the ProxyName parameter
is not configured, the proxy's IP address is used as the host name
in the REGISTER Request-URI.
Determines whether the device switches back to the primary
Proxy after using a redundant Proxy.

[0] Parking = (Default) The device continues working with a
redundant (now active) Proxy until the next failure, after which
it works with the next redundant Proxy.

[1] Homing = The device always tries to work with the primary
Proxy server (i.e., switches back to the primary Proxy
whenever it's available).
Note: To use this Proxy Redundancy mechanism, you need to
enable the keep-alive with Proxy option, by setting the parameter
EnableProxyKeepAlive to 1 or 2.
Defines the periodic rate (in seconds) at which the device
performs DNS queries to resolve FQDNs (host names) into IP
addresses. For example, if a Proxy Set is configured with an
FQDN and the parameter is configured to 60, the device queries
the DNS server every 60 seconds, which refreshes the Proxy
Set's list of DNS-resolved IP addresses.
The valid value is 0, or 5 to 2,000,000. The default is 60. The
value 0 disables periodic DNS queries and DNS resolution is
done only once - upon device reset, device power up, or new and
modified configuration.
Determines whether the device falls back to the Tel-to-IP Routing
table for call routing when Proxy servers are unavailable.

[0] Disable = (Default) Fallback is not used.

[1] Enable = The Tel-to-IP Routing table is used when Proxy
servers are unavailable.
When the device falls back to the Tel-to-IP Routing table, it
continues scanning for a Proxy. When the device locates an
active Proxy, it switches from internal routing back to Proxy
routing.
Note: To enable the redundant Proxies mechanism, set the
parameter EnableProxyKeepAlive to 1 or 2.
Determines whether the device's routing table takes precedence
over a Proxy for routing calls.
