Configure the maximum bit rate (in kb/s) for video calls. The default setting is 384.
Select to enable video support in SIP calls. The default setting is "Yes".
If enabled, when rejecting an incoming INVITE or REGISTER request, the
UCM630X 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 does not 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 call back 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.
Configure the UCM to forward HOLD requests instead of processing holds
internally. This serves to meet the standards set by some providers that require
HOLD requests to be passed along from endpoint to endpoint. This option is
disabled by default.
Note: Enabling this option may cause hold retrieval issues and MOH to not be
heard.
