Parameter Description
section):

TLS: "_sipinternaltls_tcp.<domain>" and "_sip_tls.<domain>". For
example, if the configured domain name (in the 'Proxy Address'
parameter) is "ms-server.com", the device queries for
"_sipinternaltls_tcp.ms-server.com" and "_sip_tls.ms-server.com".

TCP: "_sipinternal._tcp.<domain>" and "_sip_tcp.<domain>".

Undefined: "_sipinternaltls_tcp.<domain>",
"_sipinternal_tcp.<domain>", "_sip_tls.<domain>" and
"_sip_tcp.<domain>".
The SRV query returns the host names (and their weights). The device
then performs DNS A-record queries per host name (according to the
received weights) to resolve into IP addresses.
Note: An SRV query can return up to four host names. For each host name,
the subsequent DNS A-record query can resolve into up to 15 IP addresses.
However, the device supports up to 30 DNS-resolved IP addresses. If the
device receives more than this number of IP addresses, it uses the first 30 IP
addresses in the received list and ignores the rest.
Proxy Hot Swap
[ProxySet_IsProxyHot
Swap]
Enables the Proxy Hot-Swap feature, whereby the device switches to a
redundant proxy upon a failure in the primary proxy (no response is
received).
 [0] No = (Default) Disables the Proxy Hot-
Swap feature. If a failure occurs
in te primary proxy, the device does not connect with any other address
(proxy) configured for the Proxy Set.
 [1] Yes = The device sends the SIP INVITE/REGISTER message to the
first address listed in the Proxy Address table configured for the Proxy
Set. If a SIP response is received and this response code is defined in
the 'Keep-Alive Failure Responses' parameter (in this table), the device
assumes the proxy is down and sends the message again; otherwise, the
device assumes the proxy is up and does not send the message again.
Each time a defined response code is received, the device re-sends the
message. This can occur until a user-defined maximum number of
retransmissions (see the HotSwapRtx parameter), after which the device
sends the same message to the next address in the list, and so on. If
there is no response from any of the Proxies, the device goes through the
list again until a "live" proxy is located.
Keep-Alive Failure
Responses
[ProxySet_KeepAliveF
ailureResp]
Defines SIP response codes that if any is received in response to a keep-
alive message using SIP OPTIONS, the device considers the proxy as
down.
Up to three response codes can be configured, where each code is
separated by a comma (e.g., 407,404). By default, no response code is
defined. If no response code is configured, or if response codes received are
not those configured, the proxy is considered "alive".
Note: The SIP 200 response code is not supported for this feature.
Classification Input
[ProxySet_Classificati
onInput]
Defines how the device classifies incoming IP calls to the Proxy Set.
 [0] IP Only = (Default) Classifies calls to the Proxy Set according to IP
address only.
 [1] IP + Port + Transport = Classifies calls to the Proxy Set according to
IP address, port, and transport type.
Notes:
 The parameter is applicable only if the IP Group table's parameter,
'Classify by Proxy Set' is set to Enable (see Configuring IP Groups on
