Cisco 300-815 CLACCM key terms

A dial plan object that matches dialed digits and tells Cisco Unified Communications Manager where to send the call, either to a gateway, trunk, or another route list. It can discard or prefix digits before sending.

An ordered collection of gateways or trunks that share the same routing characteristics. A route list points to one or more route groups so calls can overflow when the first device is unavailable.

A prioritized list of route groups that a route pattern references. It defines the order in which groups are tried, enabling failover and distribution across gateways or trunks.

A Cisco IOS gateway configuration object that defines a matching rule for inbound or outbound calls. POTS peers point to voice ports, while VoIP peers point to IP destinations such as SIP or H.323 endpoints.

A dial peer on a voice gateway that associates dialed digits with a physical voice port, such as an FXO, FXS, or T1/E1 interface, to reach the PSTN or analog devices.

A dial peer that routes calls over an IP network to a SIP or H.323 device. It specifies the destination pattern, session protocol, and target address such as an IP address or DNS name.

The digit string, often including wildcards, that a dial peer uses to match dialed numbers. It determines which peer handles a call during digit-by-digit matching.

The command in a VoIP dial peer that identifies where the call is sent, typically an IP address, DNS name, or SIP URI. It pairs with the session protocol to define the signaling path.

A CUCM dial plan element that transforms dialed digits, such as adding an area code or stripping an access code, before the call is routed. It can also apply calling search space and partition changes.

A logical grouping of directory numbers and route patterns in CUCM. Partitions control which numbers are reachable by grouping them so that calling search spaces can include or exclude them.

An ordered list of partitions that determines which dialed numbers a device or line is allowed to reach. It is the primary tool for implementing class of service in CUCM.

A policy that limits which destinations a user or device may call, such as blocking international or premium numbers. In CUCM it is enforced through partitions and calling search spaces.

The CUCM process that compares dialed digits against configured patterns, considering partitions, calling search spaces, and urgent priority, to select the best matching route pattern or translation pattern.

The number of trailing digits a gateway uses to match an inbound call to a dial peer when the full number is not needed. It controls how much of the called number is examined.

A Cisco IOS rule that matches digit patterns and rewrites them, for example converting a national number to an international format. Rules are grouped into translation profiles applied to voice ports or dial peers.

A named set of voice translation rules applied to a dial peer or voice port. It can transform called, calling, or redirecting numbers on inbound or outbound calls.

A CUCM trunk configured to connect to a SIP service provider or another SIP system. It carries calls over IP using SIP signaling and typically references a route group for routing.

A CUCM gateway configuration that uses the H.323 protocol to connect to an IOS voice gateway for PSTN or intercluster calls. It is an alternative to SIP trunks for gateway connectivity.

A gateway whose endpoints are controlled by CUCM using the Media Gateway Control Protocol. CUCM manages the dial peers and endpoint configuration, simplifying gateway administration.

A CUCM feature that lets an IP phone use different location, region, and calling search space settings when it roams to another site, based on the device it is physically connected to.

A CUCM configuration container that groups devices sharing common settings such as region, location, date/time group, and calling search space. It simplifies bulk changes to many phones.

A CUCM setting that controls which codecs are allowed between devices in different regions, managing bandwidth per call for audio and video streams.

A CUCM object that defines the total bandwidth available for calls between sites. It performs call admission control so that voice and video traffic does not exceed the WAN link capacity.

A mechanism that limits the number or bandwidth of concurrent calls across a WAN link to protect voice quality. In CUCM it is implemented with locations or with the enhanced location CAC feature.

A CUCM feature that lets users log in to any supported phone and receive their own directory number, speed dials, and services. The phone temporarily adopts the user's profile.

A CUCM object that stores a user's line and service settings for Extension Mobility. When the user logs in, the profile is applied to the visited phone.

A CUCM feature that extends a user's desk phone number to a mobile phone, allowing calls to ring both devices and enabling mid-call handoff between them.

A mobility feature that rings a user's mobile phone simultaneously with the desk phone when the business number is dialed, so the user can answer from either device.

A CUCM configuration that associates an external number, such as a mobile phone, with a user's desk phone for mobility features like Single Number Reach and mid-call handoff.

A Cisco collaboration client that provides softphone, instant messaging, presence, and conferencing. It can register to CUCM as a desk phone or use Mobile and Remote Access.

A Cisco architecture that lets Jabber clients register and place calls from outside the corporate network without a VPN, using Expressway traversal of the firewall.

A Cisco appliance or virtual application that provides firewall traversal for collaboration services. The Expressway-C sits inside the network and the Expressway-E sits in the DMZ.

A connection between an Expressway-C and Expressway-E that carries signaling and media for Mobile and Remote Access. It uses the Assent or H.460.18/19 protocols for firewall traversal.

An encryption protocol for voice and video media that provides confidentiality, message authentication, and replay protection for RTP streams using keys exchanged during call setup.

A cryptographic protocol that secures signaling between CUCM and endpoints or gateways, protecting SIP messages from eavesdropping and tampering. It is configured through security profiles.

A CUCM configuration that defines the security mode (non-secure, authenticated, or encrypted) and TLS settings for a SIP trunk or endpoint, controlling how signaling is protected.

A CUCM service that issues and manages certificates for phones and other endpoints, enabling secure signaling and media. It can install, upgrade, or delete endpoint certificates.

Controls that restrict unauthorized long-distance or international calling, such as partitions, calling search spaces, and time-of-day routing. It protects the organization from costly misuse of trunks.

A CUCM feature that applies different routing or restrictions based on the time and day, using time periods and time schedules assigned to partitions.
