Valid Range and Description
ProxyRedundancyMode
[Redundancy Mode]
0 = Parking mode: gateway continues working with the last active Proxy until the next
failure. (default)
1 = Homing mode: gateway always tries to work with the primary Proxy server
(switches back to the primary Proxy whenever it is available).
Note:
To use ProxyRedundancyMode, enable Keep-alive with Proxy option
(EnableProxyKeepAlive=1).
IsTrustedProxy
[Is Proxy Trusted]
This parameter isn’t applicable and must always be set to 1.
The parameter ‘AssertedIdMode’ should be used instead.
IsFallbackUsed
[ Enable Fallback to
Routing Table ]
0 = Gateway fallback is not used (default).
1 = Internal Telephone to IP Routing table is used when Proxy servers are not
available.
When the gateway falls back to the internal Telephone to IP Routing table, the gateway
continues scanning for a Proxy. When the gateway finds an active Proxy, it switches
from internal routing back to Proxy routing.
Note:
To enable the redundant Proxies mechanism set ‘EnableProxyKeepAlive’ to 1.
UserName
[User Name] Username used for Registration and for Basic/Digest authentication process with Proxy
/ Registrar.

server.
RegistrarName

Typically a value of 3600 is assigned, for one hour registration.
The gateway resumes registration when half the defined timeout period expires.

[Re-registration Timing (%)] Defines the re-registration timing (in percentage). The timing is a percentage of the re-
register timing set by the Registration server.
The valid range is 50 to 100. The default value is 50.
For example: If ‘RegistrationTimeDivider = 70’ (%) and Registration Expires time =
3600, the gateway resends its registration request after 3600 x 70% = 2520 sec.
RegistrationRetryTime
[Registration Retry Time]
Defines the time period (in seconds) after which a Registration request is resent if
registration fails with 4xx, or there is no response from the Proxy/Registrar.The default

Note 2: The Mediant 2000 sends PRACK message if 180/183 response is received
with “100rel” in the Supported or the Required headers.
