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.
