Mediant 1000 Gateway & E-SBC | User's Manual
Description
Note: If you configure the 'Authentication Mode'
parameter to SBC as Server, you can specify the SIP
request (method) types (e.g., INVITE) that must be
challenged by the device, using the IP Group's
'Authentication Method List' parameter.
Defines the routing mode after a call redirection (i.e., a
3xx SIP response is received) or transfer (i.e., a SIP
REFER request is received).
■ [-1] = Not Configured (Default)
■ [0] Standard = INVITE messages that are
generated as a result of Transfer or Redirect are sent
directly to the URI, according to the Refer-To header
in the REFER message or Contact header in the 3xx
response.
■ [1] Proxy = Sends a new INVITE to the Proxy. This
is applicable only if a Proxy server is used and the
parameter [AlwaysSendtoProxy] is set to [0].
■ [2] Routing Table = Uses the Routing table to
locate the destination and then sends a new INVITE
to this destination.
Note:
■ When the parameter is configured to [1] and the
INVITE sent to the Proxy fails, the device re-routes
the call according to the Standard mode [0].
■ When the parameter is configured to [2] and the
INVITE fails, the device re-routes the call according
to the Standard mode [0]. If DNS resolution fails, the
device attempts to route the call to the Proxy. If
routing to the Proxy also fails, the Redirect / Transfer
request is rejected.
■ When the parameter is set to [2], the XferPrefix
parameter can be used to define different routing
rules for redirected calls.
■ The parameter is ignored if the parameter
[AlwaysSendToProxy] is set to [1].
Defines the Request-URI host name in outgoing INVITE
messages.
■ [0] No (default).
■ [1] Yes = The device uses the IP address (or domain
name) defined in the Tel-to-IP Routing table (see
Configuring Tel-to-IP Routing
Request-URI host name in outgoing INVITE
messages, instead of the value configured in the
'SIP Group Name' field.
Note: The parameter is applicable only to Server-type IP
Groups.
