CHAPTER72 Configuration Parameters Reference
Mediant 800 Gateway & E-SBC | User's Manual
Parameter Description
'Set Out-Of-Service On
Registration Failure'
configure voip > sip-
definition proxy-and-
registration > set-oos-
on-reg-failure
[OOSOnRegistrationFail]
Enables setting the endpoint, trunk, or entire device
(i.e., all endpoints) to out-of-service if registration fails.
■ [0] Disable (default)
■ [1] Enable
If the registration is per endpoint (i.e.,
AuthenticationMode is set to 0) or per Account (see
Configuring Trunk Group Settings) and a specific
endpoint/Account registration fails (SIP 4xx or no
response), then that endpoint is set to out-of-service
until a success response is received in a subsequent
registration request. When the registration is per the
entire device (i.e., AuthenticationMode is set to 1) and
registration fails, all endpoints are set to out-of-service.
If all the Accounts of a specific Trunk Group fail
registration and if the Trunk Group comprises a
complete trunk, then the entire trunk is set to out-of-
service.
Note:
■ The parameter is applicable only to the Gateway
application.
■ The out-of-service method is configured using the
FXSOOSBehavior parameter.
configure voip > sip-
definition proxy-and-
registration > expl-un-
reg
[UnregistrationMode]
Enables the device to perform explicit unregisters.
■ [0] Disable (default)
■ [1] Enable = The device sends an asterisk ("*")
value in the SIP Contact header, instructing the
Registrar server to remove all previous registration
bindings. The device removes SIP User Agent (UA)
registration bindings in a Registrar, according to
RFC 3261. Registrations are soft state and expire
unless refreshed, but they can also be explicitly
removed. A client can attempt to influence the
expiration interval selected by the Registrar. A UA
requests the immediate removal of a binding by
specifying an expiration interval of "0" for that
contact address in a REGISTER request. UA's
should support this mechanism so that bindings can
be removed before their expiration interval has
passed. Use of the "*" Contact header field value
allows a registering UA to remove all bindings
associated with an address-of-record (AOR) without
knowing their precise values.
Note: The REGISTER-specific Contact header field
value of "*" applies to all registrations, but it can only be
used if the Expires header field is present with a value
of "0".
'Add Empty Authorization Header' Enables the inclusion of the SIP Authorization header in
initial registration (REGISTER) requests sent by the
device.
