Mediant 3000
Parameter
Description
[1]
SRV
[2]
NAPTR
If set to A-Record
[0],
no NAPTR or SRV queries are performed.
If set to SRV
[1]
and the Proxy/Registrar IP address parameter,
Contact/Record-Route headers, or IP address defined in the Routing
tables contain a domain name, an SRV query is performed. The device
uses the first host name received from the SRV query. The device then
performs a DNS A-record query for the host name to locate an IP
address.
If set to NAPTR
[2],
an NAPTR query is performed. If it is successful, an
SRV query is sent according to the information received in the NAPTR
response. If the NAPTR query fails, an SRV query is performed
according to the configured transport type.
If the Proxy/Registrar IP address parameter, the domain name in the
Contact/Record-Route headers, or the IP address defined in the
Routing tables contain a domain name with port definition, the device
performs a regular DNS A-record query.
If a specific Transport Type is defined, a NAPTR query is not
performed.
Note:
To enable NAPTR/SRV queries for Proxy servers only, use the
parameter ProxyDNSQueryType.
Web: Proxy DNS Query
Type
[ProxyDNSQueryType]
Enables the use of DNS Naming Authority Pointer (NAPTR) and
Service Record (SRV) queries to discover Proxy servers.
[0]
A-Record (default)
[1]
SRV
[2]
NAPTR
If set to A-Record
[0],
no NAPTR or SRV queries are performed.
If set to SRV
[1]
and 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. Therefore, if the first SRV query returns two
domain names and the A-record queries return two IP addresses each,
no additional searches are performed.
If set to NAPTR
[2],
an NAPTR query is performed. If it is successful, an
SRV query is sent according to the information received in the NAPTR
response. If the NAPTR query fails, an SRV query is performed
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:
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
[UseGatewayNameForO
ptions]
Determines whether the device uses its IP address or gateway name in
keep-alive SIP OPTIONS messages.
[0]
No = (Default) Use the device's IP address in keep-alive
OPTIONS messages.
[1]
Yes = Use 'Gateway Name' (SIPGatewayName) in keep-alive
OPTIONS messages.
