User's Manual
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
272).

When enabled, NAPTR/SRV queries are used to discover
Proxy servers even if the parameter DNSQueryType is
disabled.
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). The "gateway name" is
configured using 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 address is used in the From and To
headers in keep-alive OPTIONS messages.
Defines the user name used for registration and Basic/Digest
authentication with a Proxy/Registrar server.
By default, no value is defined.
Notes:

This parameter is applicable only to the Gateway
application.

This parameter is applicable only if single device
registration is used (i.e., the parameter AuthenticationMode
is set to authentication per gateway).

Instead of configuring this parameter, the Authentication
