domains are accepted and sent to the default context or the context
associated with the user/peer placing the call. Register to non-local
domains will be automatically denied if a domain list is configured. Up to 10
domains can be added.
Configure the domain in the "From:" header of the SIP message. It may be
required by some providers for authentication.
If enabled, the UCM6510 will add local host name and local IP to domain
list. The default setting is "No".
If enabled, requests for external domains that are not served by the
UCM6510 will be allowed. The default setting is "Yes".

Table 71: SIP Settings/Misc

Configure the register retry timeout (in seconds). The default setting is 20.
Configure the number of registration attempts before the UCM6510 gives
up. The default setting is 0, which means the UCM6510 will keep trying
until the server side accepts the registration request.
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, the UCM6510 will generate manager events when SIP UA
performs events (e.g. Hold). The default setting is "No".
If enabled, when rejecting an incoming INVITE or REGISTER request, the
UCM6510 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".

Table 72: SIP Settings/Session Timer
