Mediant 500 MSBR
routing tables contain a domain name with a port definition, the
device performs a regular DNS A-record query.

If a specific Transport Type is configured, a NAPTR query is not
performed.

To enable NAPTR/SRV queries for Proxy servers only, use the
global parameter ProxyDNSQueryType, or use the Proxy Sets table.
Proxy DNS Query Type
configure voip > sip-
definition proxy-and-
registration > 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.
Note:

This functionality can be configured per Proxy Set in the Proxy Sets
table (see Configuring Proxy Sets on page 348).

When enabled, NAPTR/SRV queries are used to discover Proxy
servers even if the parameter DNSQueryType is disabled.
Use Gateway Name for
OPTIONS
configure voip > sip-
definition settings > use-
gw-name-for-opt
[UseGatewayNameForOp
tions]
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 address is used in the From and To headers
in keep-alive OPTIONS messages.
User Name
configure voip > sip-
definition proxy-and-
registration > user-name-
4-auth
[UserName]
Defines the username for registration and Basic/Digest authentication
with a Proxy/Registrar server.
By default, no value is defined.
Note:

The parameter is applicable only to the Gateway application.

The parameter is applicable only if single device registration is used
(i.e., the parameter AuthenticationMode is set to authentication per
gateway).

Analog interfaces: Instead of configuring the parameter, the
Authentication table can be used (see Authentication on page 601).
Password Defines the password for Basic/Digest authentication with a
