Parameter Description
Web: Proxy DNS Query Type
CLI: proxy-dns-query
[ProxyDNSQueryType]
Global parameter that defines the DNS query record type for
resolving the Proxy server's configured domain name (FQDN)
into an IP address.
 [0] A-Record (default) = A-record DNS query.
 [1] SRV = If the Proxy IP address parameter contains a
domain name without port definition (e.g., ProxyIP =
domain.com), an SRV query is performed. The SRV query
returns up to four Proxy host names and their weights. The
device then performs DNS A-record queries for each Proxy
host name (according to the received weights) to locate up
to four Proxy IP addresses. Thus, if the first SRV query
returns two domain names and the A-record queries return
two IP addresses each, no additional searches are
performed.
 [2] NAPTR = NAPTR query is done. If successful, an SRV
query is sent according to the information received in the
NAPTR response. If the NAPTR query fails, an SRV query
is done according to the configured transport type. If the
Proxy IP address parameter contains a domain name with
port definition (e.g., ProxyIP = domain.com:5080), the
device performs a regular DNS A-record query. If a specific
Transport Type is defined, a NAPTR query is not
performed.
Notes:
 This functionality can be configured per Proxy Set in the
Proxy Set table (see ''Configuring Proxy Sets'' on page
297).
 When enabled, NAPTR/SRV queries are used to discover
Proxy servers even if the parameter DNSQueryType is
disabled.
Web/EMS: Use Gateway Name for
OPTIONS
CLI: use-gw-name-for-opt
[UseGatewayNameForOptions]
Determines whether the device uses its IP address or string
name ("gateway name") in keep-
alive SIP OPTIONS messages
(host part of the Request-URI). To configure the "gateway
name", use the SIPGatewayName parameter. The device uses
the OPTIONS request as a keep-alive message with its
primary and redundant SIP proxy servers (i.e., the
EnableProxyKeepAlive parameter is set to 1).
 [0] No = (Default) Device's IP address is used in keep-alive
OPTIONS messages.
 [1] Yes = Device's "gateway name" is used in keep-alive
OPTIONS messages.
 [2] Server = Device's IP add
ress is used in the From and To
headers in keep-alive OPTIONS messages.
