Session Refresher
If enabled, when rejecting an incoming INVITE or REGISTER request, the
UCM6200 will always reject with "401 Unauthorized" instead of notifying the
requester whether there is a matching user or peer for the request. This reduces
the ability of an attacker to scan for valid SIP usernames. The default setting is
"No".
If enable, and if the service doesn't know the attribute of FEC/FECC/BFCP, then
the attribute will be passthrough.
If enabled, call negotiation will use final response SDP.
If enabled, the UCM will callback to the transferrer when blind transfer fails
(reason of failure includes: busy and no answer).
Note: This feature takes effect only on internal calls.
Configure the timeout in (s) for the transferrer waiting for the destination to
answer. Default is 60s.
