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
258).

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 gateway
name in keep-alive SIP OPTIONS messages.

[0] No = (Default) The device's IP address is used in keep-
alive OPTIONS messages.

[1] Yes = 'Gateway Name' (configured by the
SIPGatewayName parameter) is used in keep-alive
OPTIONS messages.

[2] Server = The device's IP address is used in the From
and To SIP headers in keep-alive OPTIONS messages.
The OPTIONS Request-URI host part contains either the
device's IP address or a string defined by the
SIPGatewayName parameter. The device uses the OPTIONS
request as a keep-alive message to its primary and redundant
Proxies (i.e., the EnableProxyKeepAlive parameter is set to 1).
Note: This parameter is applicable only to the Gateway
application.
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
