Типы маршрутов в UCM

Directory Numbers

Numbers assigned to all endpoints and applications; used for internal routing within a cluster

Translation Pattern

Used to translate a dialed number and then look up the translated number in the call routing table again

Route Pattern Used to route calls to off-net destinations (via a gateway) or to other Unified CM clusters (via a trunk)

Hunt Pilot Used to route calls to hunt group members based on a distribution algorithm (longest-idle, circular, etc)

Call Park Numbers

Allows placing a call on hold to a number and retrieving back the call from other phone by dialing the number

Meet-Me Numbers

Allows a conference call initiator to set up a conference call and attendees to join the conference by dialing the conference number

Типы источников вызова в UCM

IP Phones A number dialed by an IP phone is looked up in the routing table.

Trunks A call request received through a trunk is looked up in the routing table.

Gateways A call request received from a gateway is looked up in the call routing table.

Translation Patterns

After a translation pattern was best matched (as a target of a call routing table lookup), the transformed number is looked up again in the call routing table. The entity that generates this lookup is the translation pattern.

Специальные символы в маршрутах Wildcard Description

x Single digit (0–9, *, #)

@ North American Numbering Plan

! One or more digits (0–9)

[x-y] Generic range notation

[^x-y] Exclusion range notation

. Terminates access code

# Terminates interdigit timeout

<wildcard>? Matches zero or more occurrences of any digit that matches the previous wildcard

<wildcard>+ Matches one or more occurrences of any digit that matches the previous wildcard

\+ Matches the + sign as part of a number; used for globalized E.164 call routing.

Разграничение прав доступа к маршрутам

Партиция – часть базы данных с телефонными номерами с одинаковой достижимостью

CSS – список партиций, который определяет права доступа телефона или пользователя

По умолчанию! все маршруты находятся в одной партиции <None> все источники вызова имеют один CSS <None> содержащий партицию <None>

Основное правило маршрутизации

Наличие доступа к маршруту!

Правило наиболее точного совпадения!

Настройка Urgent Priority может влиять на это правило

User C dials “1234”

User B dials “1212”

User A dials “1200”

Digit Manipulation Element Characteristics

External Phone Number Mask Designates the fully qualified E.164 address for the user extension –  Part of Calling/Called Transformation settings.

Digit Prefix and Stripping Prefix or strip dialed digits from a route or translation pattern for outbound calls –  Part of Calling/Called Transformation settings.

Transformation Masks Manipulate the dialed digits or calling party number –  Part of Calling/Called Transformation settings.

Translation Pattern

When dialed digits match the translation pattern, Unified CM performs the translation first and then routes the call again. Make use of the Calling/Called Transformation settings for digit manipulation.

Significant Digits Strip off digits received by Unified CM for incoming calls from a PSTN gateway or from a trunk.
