(E.g. PBX Phones)
Call Park uses orbits (internal numbers not assigned to users) for parking calls
Orbits are scoped at the pool level by assigning the range to the Call Park Service running on the front ends
Have enough orbits so that any one orbit is not reused too quickly
Assigning DID numbers as orbit numbers is not supported
No need to define an orbit range for every pool but must disable call park service on pools that do not have ranges
defined
Comparison/Caveats
•
•
No parking in a known destination or at another extension
No pickup from any ringing extension
•
Create and Manage an Unassigned Numbers List
For Example :
• Unprovisioned Numbers
• Decommissioned Numbers
• Blocked Numbers
•
•
Location used for Presence, Emergency Routing, or both
Populating LIS database with (in order of preference):
•
•
•
•
•
•
•
Powershell manual or CSV (no Lync Control Panel Support) for configuring LIS
Location Policy is needed for enabling E911 and routing

Emergency Calls are routed via SIP to Emergency Service Provider – includes the location
Include Security Desk IM alter and conference
Requires obtaining routing service from a provider
Can be used for location based emergency routing outside of United States
• Admins can natively control what Caller ID is presented to the
receiving party (PSTN/PBX):
• Per user/group controls to suppress/alter calling party number by a route
setting
• Granular controls based on callers and destination number:
•
•
Alice calls an external PSTN number, caller ID is presented as +1 425 555 0100
Alice calls an internal PBX number, caller ID is presented as +1 425 555 2302
• Override for “simultaneous ringing”: Bob calls Alice, who has caller id
masked for external calls and also has simultaneous ringing configured;
Bob’s caller-id is presented to Alice’s mobile device

Dial Plans
Known as the location profile in OCS 2007 R2
A set of normalization rules that translate dial strings to full, unique numbers
(E.164) that are required by the routing and authorization applications of Lync
Lync clients normalize dialed numbers before they are sent to the server
Normalization rules are specified using regular expressions
^
match the start
$
match the end
\d
match any digit
\d*
0 or more digits
\d{5}
any 5 digits
[135]
1, 3, or 5
[1..5]
1 through 5
(13)|(17) 13 or 17
(…)
“captures” the enclosed characters for referring
to them in the result as $1, $2, $3, etc.
21
Planning for Dial Plans
Identify all areas within the organization that have local
dialing requirements
Identify the valid number patterns for each
Try to standardize on an organization wide scheme
Determine the Dial Plan Scoping strategy
Dial Plans are obtained by UC clients through the inband
provisioning process via the scope of the Dial Plan policy
Dial Plan Scope
The most specific policy available
will be applied
User policy will be assigned or it will
be set to <Automatic> to allow
selection from Pool, Site, or Global
policies
Generally user based scopes are
preferred even for survivable
branches
Consistent operational practice
Users won’t pick up different Dial Plans
when roaming or the SBA goes offline

Voice Policy Scope
The most specific policy available

Generally user based scopes are
preferred even for survivable
branches
Consistent operational practice
Users won’t pick up different Voice
Policies when roaming or the SBA goes
offline
The PSTN Usages provide the link
between the user and outbound
routes – at least one is required.
The ordering of PSTN usages is
important because outbound routing
does usage matching from the top
down.

Planning for PSTN Usages
PSTN Usages are just call permission descriptive labels
These are generally based on the PSTN cost
Identify all call permissions that are required in the organization –
create a PSTN Usage for each
Should be contextual
Local in context such as Atlanta Local
Regional in context like US Long Distance
The result should be that there are PSTN Usages defined that meet
the dialing authorization needs of the organization
Can establish priority of routes by ordering usages that can route
the same called number
Planning Voice Routes
Routes are needed to route the destination numbers listed in the Dial Plans
There should be no Dial Plan numbers that don’t match users, orbits, unassigned numbers,
or routes
Regular expressions are also used in Routes to specify the dialed number to match
Each Route is required to have the FQDN of one or more gateways which
support the route
Calls will be evenly distributed between multiple gateways in a given route
Each Route gets assigned the PSTN Usage records that users must have in
order to call the numbers served by the Route
US Long Distance
Route resiliency can be done with multiple Usage’s
User’s first Usage grants “Local Calling”
User’s second Usage grants “Long Distance Calling” – can also reach local numbers
Least Cost Routing is supported by associating numbers to specific gateways
Europe countries codes could egress from a single gateway for example
Voice Policies

• Voice feature set
PSTN Usages
• Purpose (usage,
caller’s intent)
• Priority

PSTN Usage Planning
PSTN Usages are just call permission descriptive labels
These are generally based on the PSTN cost
Identify all call permissions that are required in the organization –
create a PSTN Usage for each
Should be contextual
Local in context such as Atlanta Local or Atlanta Toll
Regional in context like US Long Distance
Internal calls
The result should be the required number of PSTN Usages needed
for assigning to users (via Voice Policies) that meet the dialing
authorization needs of the organization
Can establish priority of routes by ordering usages that can route
the same called number
Voice Route Planning
A route is needed to adequately route destination numbers that are listed in the
Dial Plans
There should be no Dial Plan numbers that don’t match users, orbits, unassigned numbers,
or routes
Regular expressions are also used in Routes to identify the dialed number to
which a Route will be applied
Each Route is required to have the FQDN of one or more gateways which
support the route
Calls will be evenly distributed between multiple gateways in a given route
Each Route gets assigned the PSTN Usage records that users must have in
order to call the numbers served by the Route
US Long Distance
Least Cost Routing is supported by associating numbers to specific gateways
Europe countries codes could egress from a single gateway for example
Resiliency is supported by listing more than one gateway per route
