which can direct the call to a specific context if desired. By default, all
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.
From Domain
Configure the domain in the "From:" header of the SIP message. It may
be required by some providers for authentication.
Auto Domain
If enabled, the UCM6510 will add local host name and local IP to domain
list. The default setting is "No".
Allow External Domains
If enabled, requests for external domains that are not served by the
UCM6510 will be allowed. The default setting is "Yes".

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 UCM6510
gives up. The default setting is 0, which means the UCM6510 will keep
trying until the server side accepts the registration request.
Video
Max Bit Rate (kb/s)
Configure the maximum bit rate (in kb/s) for video calls. The default
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 UCM6510 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 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".
