Mediant 1000 & Mediant 600
Parameter Description
Registration Time
Threshold
[RegistrationTimeThr
eshold]
Defines a threshold (in seconds) for re-registration timing. If this parameter is
greater than 0, but lower than the computed re-registration timing (according
to the parameter RegistrationTimeDivider), the re-registration timing is set to
the following: timing set by the Registration server in the Expires header
minus the value of the parameter RegistrationTimeThreshold.
The valid range is 0 to 2,000,000. The default value is 0.
Re-register On INVITE
Failure
[RegisterOnInviteFail
ure]
Enables immediate re-registration if a failure response is received for an
INVITE request sent by the device.
 [0] Disable = Disabled (default)
 [1] Enable = Enabled
Miscellaneous parameters
Gateway Name
[SIPGatewayName]
Assigns a name to the device (e.g., 'gateway1.com'). Ensure that the name
you choose is the one with which the Proxy is configured to identify the
device.
Note: If specified, the device name is used as the host part of the SIP URI in
the From header. If not specified, the device's IP address is used instead
(default).
Gateway Registration
Name
[GWRegistrationNam
e]
Defines the user name that is used in the From and To headers in
REGISTER messages. If no value is specified (default) for this parameter,
the UserName parameter is used instead.
Note: This parameter is applicable only for single registration per device (i.e.,
AuthenticationMode is set to 1). When the device registers each channel
separately (i.e., AuthenticationMode is set to 0), the user name is set to the
channel's phone number.
DNS Query Type
[DNSQueryType]
Enables the use of DNS Naming Authority Pointer (NAPTR) and Service
Record (SRV) queries to resolve Proxy and Registrar servers and to resolve
all domain names that appear in the Contact and Record-Route headers.
 [0] A-Record = A-Record (default)
 [1] SRV = SRV
 [2] NAPTR = 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 contains
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 contains 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.
