AudioCodes MediaPack MP-118 User Manual

Version 6.6 463 MP-11x & MP-124
User's Manual 43. Configuration Parameters Reference
Parameter Description
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
[UseGatewayNameForOptions]
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.
