AOR
Address of Record
Address of Record
A SIP or SIPS URI that points to a domain with a location service that can map the URI
to another URI where the user might be available. Typically, the location service is
populated through registrations. An AOR is frequently thought of as the “public
address” of the user.

Assent
Cisco’s proprietary protocol for firewall traversal.
B2BUA
Back-to-back user agent
Back-to-back user agent
A back-to-back user agent operates between both end points of a SIP call and divides
the communication channel into two independent call legs. Unlike a proxy server, a
B2BUA maintains complete state for the calls it handles. A B2BUA typically provides
more features than a proxy server, such as media interworking.

CAC
Common Access Card
Common Access Card
A CAC is a smart card (or similar) device that contains a user's unique certificate and
private key. Access to the certificate and key is granted by entering a PIN code and the
certificate is used in mutual authentication with other systems to prove the identity of
the user. This is classed as two-factor authentication as the user needs both the CAC
and the PIN to access its contents.

Conductor
Conductor
The Cisco TelePresence Conductor lies within your video communications network
between a VCS and a pool of MCUs. It allows administrators to configure the network
so that users can dial a specified conference alias from an endpoint and be taken
straight into a conference hosted on an MCU.
