Description
d. The special prefix is removed before the resultant
INVITE is sent to the destination ((transfer target).
■ [2] IP Group Name = Changes the host part in the
REFER message to the name configured for the IP
Group (in the IP Groups table).
■ [3] Handle Locally = Handles the incoming REFER
request itself without forwarding the REFER. The
device generates a new INVITE to the alternative
destination (transfer target) according to the rules in the
IP-to-IP Routing table (the 'Call Trigger' parameter
must be set to REFER).
■ [4] Local Host = In the REFER message received
from the transferor, the device replaces the Refer-To
header value (URL) with the IP address of the device or
with the 'Local Host Name' parameter value configured
for the IP Group (transferee) to where the device
forwards the REFER message. This ensures that the
transferee sends the re-routed INVITE back to the
device which then sends the call to the transfer target.
■ [5] Keep URI (user@host) = The device forwards the
REFER message without changing the URI
(user@host) in the SIP Refer-To header. If you
configure the 'Remote Replaces Mode' parameter (see
below) to any value other than Keep as is, the
devicemay modify the 'replaces' parameter of the
Refer-To header to reflect the call identifiers of the leg.
This applies to all types of call transfers (e.g., blind and
attendant transfer).
Note:
■ You can override the parameter's settings using
Message Manipulation rules configured with the
AudioCodes proprietary SIP header, X-AC-Action. For
more information, see
Action Header on page 837.
■ The corresponding global parameter is
[SBCReferBehavior].
Enables the device to handle incoming INVITEs containing
the Replaces header for the SIP entity (which does not
support the header) associated with the IP Profile. The
Replaces header is used to replace an existing SIP dialog
with a new dialog such as in call transfer or call pickup.
■ [0] Standard = (Default) The SIP entity supports
INVITE messages containing Replaces headers. The
device forwards the INVITE message containing the
Replaces header to the SIP entity. The device may
change the value of the Replaces header to reflect the
call identifiers of the leg.
