Version 7.2 1117 Mediant 800B Gateway & E-SBC
User's Manual 72. Configuration Parameters Reference
Parameter Description
The 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.
Registration Mode
configure voip > sip-definition
settings > authentication-mode
[AuthenticationMode]
Determines the device's registration and authentication method.
[0] Per Endpoint = Registration and authentication is
performed separately for each endpoint/B-channel. This is
typically used for FXS interfaces, where each endpoint
registers (and authenticates) separately with its user name
and password.
[1] Per Gateway = (Default) Single registration and
authentication for the entire device. This is typically used for
FXO interfaces and digital modules.
[3] Per FXS = Registration and authentication for FXS
endpoints.
Note: The parameter is applicable only to the Gateway
application.
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 on
page 519
) 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
settings > 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, i
nstructing 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
