5. 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

6. 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.

7. 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.

8. 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>

9. Основное правило маршрутизации
Наличие доступа к
маршруту!
Правило наиболее
точного совпадения!

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.
