SIP SETTINGS/MISC
Table 86: SIP Settings/Misc
Outbound SIP Registrations
Register Timeout Configure the register retry timeout (in seconds). The default setting is 20.
Register Attempts
Configure the number of registration attempts before the UCM6100 gives
up. The default setting is 0, which means the UCM6100 will keep trying
until the server side accepts the registration request.

setting is 384.
Support SIP Video Select to enable video support in SIP calls. The default setting is "Yes".
Generate Manager Events
If enabled, the UCM6100 will generate manager events when SIP UA
performs events (e.g. Hold). The default setting is "No".
Reject Non-Matching INVITE
If enabled, when rejecting an incoming INVITE or REGISTER request, the
UCM6100 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".
