To which of the following locations should you navigate on a Cisco TelePresence VCS if an administrator policy
denies a call that should be allowed?
A.
Call Policy > Configuration
B.
Protocols > SIP > Domains
C.
Protocols > SIP > Configuration
D.
Registration > Deny List
Explanation:
You should navigate to Call Policy > Configuration on a Cisco TelePresence Video Communication Server
(VCS) if an administrator policy denies a call that should be allowed. Administrator policies are also known as
call policies. Call policies can proxy a call to a destination, redirect a call to a different destination, or reject a
call based on its source and destination.
You should navigate to Protocols > SIP > Domains on a Cisco VCS if a domain does not exist in the list of
defined domains. If an endpoint attempts to register with a domain name that does not exist on the VCS, the
endpoint will not be allowed to register. In addition, the error message Unknown domain will appear in the event
log.
You should navigate to Protocols > SIP > Configuration on a Cisco VCS if the VCS is mistakenly attempting to
proxy registration requests to another zone. If SIP registration proxy mode is set to Proxy To Known Only or
Proxy To Any, Cisco VCS will attempt to forward registration requests to another zone. If the Cisco VCS should
not proxy registration requests, you should set SIP registration proxy mode to Off.
You should navigate to Registration > Deny List on a Cisco VCS if a restriction policy is mistakenly denyingregistration to an endpoint. This can occur if an overly broad pattern match has been configured in the Deny
List. Restriction policies are used to whitelist or blacklist endpoint aliases. If the Restriction policy setting is set
to Allow List, an endpoint will be allowed to register only if its alias matches an Allow List entry. If the Restriction
policy setting is set to Deny List, an endpoint will be allowed to register only if its alias does not match a Deny
List entry.Cisco: Cisco TelePresence Video Communication Server, Administrator Guide: About Call Policy (PDF)
