Cisco VCS Administrator Guide (X7.1)
Definition
A VCS application that enables interoperability between Microsoft Office
Communications Server (OCS) and FindMe. See the
information.
A VCS that has been configured to belong to a cluster.
An IETF proposal for securing messages using public key cryptography.
In relation to the VCS, a means of controlling the bandwidth used on a link.
In SIP, an intermediary entity that acts as both a server and a client for the purpose of
making requests on behalf of other clients. A proxy server primarily plays the role of
routing, which means its job is to ensure that a request is sent to another entity "closer"
to the targeted user. Proxies are also useful for enforcing policy (for example, making
sure a user is allowed to make a call). A proxy interprets, and, if necessary, rewrites
specific parts of a request message before forwarding it. While a proxy can set up calls
between SIP endpoints, it does not participate in the call after it is set up.
Mechanisms that give a network administrator the ability to provide different priorities
to an applications' network traffic.
A protocol used between H.323 endpoints and a gatekeeper to register and place
calls.
In SIP, a server that accepts REGISTER requests and places the information it
receives in those requests into the location service for the domain it handles. This
information is used to advise other SIP Proxies/Registrars where to send calls for that
endpoint.
A pattern used to match text strings according to a POSIX-defined syntax.
A process and result used by the IETF for Internet standards.
A commonly used standard for computer serial ports.
A control protocol for RTP. Defined by
Real time protocol designed for the transmission of voice and video. Defined by
3550.
A framework for authentication and data security in Internet protocols.
An encrypted protocol used to provide a secure CLI.
An instant messaging and presence protocol based on SIP.
