Overview

In the US, Evolve IP has two primary datacenters for its voice infrastructure.  One in Las Vegas for users located in the west, and one in Philadelphia for users located in the east.  When configuring your voice routes in Office 365, you will want to make one of the two locations a primary route and the other a secondary route.  For example:

Evolve IP uses Microsoft's multi-tenant (carrier) model for direct routing.  This type of configuration requires the use of PowerShell commands – it cannot be created in the Teams admin center.  However, after the configuration has been completed you will be able to view and manage the voice routes in the Teams admin center, but there will be no SBCs listed.

In the US, Evolve IP has two primary datacenters for its voice infrastructure.  One in Las Vegas for users located in the west, and one in Philadelphia for users located in the east.  When configuring your voice routes in Office 365, you will want to make one of the two locations a primary route and the other a secondary route.  For example:

• Users located on the east coast would use the Philadelphia (east) voice infrastructure for their primary route, and the Las
• Users located on the east coast would use the Philadelphia (east) voice infrastructure for their primary route, and the Las Vegas (west) voice infrastructure for their secondary route.
• Users located on the west coast would use the Las Vegas (west) voice infrastructure for their secondary route.
• Users located on the west coast would use the Las Vegas (west) voice infrastructure for their primary route, and the Philadelphia (east) voice infrastructure for their secondary route.
• For users located in the middle of the US, you will need to choose a primary/secondary combination that best works for their location.

The above scenarios means you will have the following configured in Office 365:

•   We recommend using the Mississippi River as a dividing line between east and west.

For our EU locations, Evolve IP has datacenters available in Amsterdam and Delft in the Netherlands.  These datacenters offer the same redundant infrastructure and we will advise you on the optimal primary route upon delivery of your unique domains.

The above means you will have the following configured for direct routing to Evolve IP:

• Qty (2) PSTN Usage objects - These objects are used to link voice routes with voice routing policies.  You will have one PSTN Usage object for the east route & policy, and one for the west route & policy.
• Qty (2) Voice Routes - A voice route for the west (
• Qty (2) PSTN Usage objects.  These objects are used to link voice routes with voice routing policies.  You will have one PSTN Usage object for the east route & policy, and one for the west route & policy.
• Qty (2) Voice Routes.  A voice route for the west (Las Vegas), and a voice route for the east (Philadelphia).
• Qty (2) Voice Routing Policies.  - One assigned to users located in the west, and one assigned to users in the east.

Naming Conventions

Every organization has its own naming conventions, and Evolve IP is no different.  The steps in this article use our naming conventions, and we strongly suggest you use them for two important reasons:

• If you need to get support from Evolve IP, our support teams will have no problem identifying, verifying, and if needed, troubleshooting your direct routing configuration.
• If sometime in the future you decide to use Evolve IP for managing your direct routing configuration and user provisioning, we can easily slip into that role.

If you choose to use your own naming conventions, that's totally fine.  We understand.

Steps to Configure Teams Direct Routing

1. Connect to the Skype for Business Online Services

1. Connect to the Microsoft Teams Services

Connect to your Microsoft Teams services using PowerShell.  If needed, review the Teams Direct Routing Connect to your Skype for Business Online services using PowerShell.  You do not need to connect to the Teams, Azure AD, or MSOL services.  If needed, review the Teams Direct Routing - 01 - Planning and Prerequisites article for configuration details.

Connect-MicrosoftTeams

2. Create the PSTN Usage Objects

A PSTN Usage object links a voice routing policy to one or more voice routes.  It doesn't do anything else, and there is no configuration associated with this object.  The Set-CsOnlinePstnUsage command is used to add/remove usages to/from the usage list. The usage list is global so it can be used by policies and routes throughout your environment.

The below creates a PSTN usage object for both the Evolve IP "East" & "West" voice infrastructures in your region.

• Get-CsOnlinePstnUsage
• Set-CsOnlinePstnUsage

Use the Below PowerShell Code Based On Your Region

# Define the PSTN Usage names, which are used throughout the configuration steps
$PstnUsageEast = "

EvolveIP-

AllCalls-

USEast"
$PstnUsageWest = "

EvolveIP-

AllCalls-

USWest"

################################
### PSTN Usage Configuration ###
################################

# Add the PSTN Usage names to the global usage list
Set-CsOnlinePstnUsage -Identity "Global" -Usage @{Add="$($PstnUsageEast)

"}
Set-CsOnlinePstnUsage -Identity "Global" -Usage @{Add="$($PstnUsageWest)"}

# View the list of PSTN Usage names
Get-CSOnlinePSTNUsage

3. Create the Voice Routes

Voice routes are associated with a PSTN Usage object.  Each voice route is assigned a priority number with the lower number having a higher priority.  Additionally, a voice route includes a number pattern (regular expression) that identifies which phone numbers will be routed through a given voice route.  To route all calls through a voice route, use this expression for the number pattern:  .*

• Get-CsOnlineVoiceRoute
• New-CsOnlineVoiceRoute
• Set-CsOnlineVoiceRoute

The below PowerShell code creates a voice route and associates it with its respective PSTN usage object.  Because each PSTN usage object is only associated with a single route in this configuration, the priority numbers configured in the voice routes have no affect.

4. Create the Voice Routing Policies

Voice Routing Policies are linked to voice routes by assigning the routing policy to one or more PSTN Usage objects.  The order of the PSTN usage objects matters.  The first PSTN usage object will be used first.

# Define the PSTN Usage names, which are used throughout the configuration steps
$PstnUsageNNpeer01 = "EvolveIP-AllCalls-NLNNpeer01"
$PstnUsageNNpeer02 = "EvolveIP-AllCalls-NLNNpeer02"

4. Create the Voice Routing Policies

Voice Routing Policies are linked to voice routes by assigning the routing policy to one or more PSTN Usage objects.  The order of the list of PSTN usage objects in a voice routing policy is important.  The first PSTN usage object will be evaluated first.

• Get-CsOnlineVoiceRoutingPolicy
• New-CsOnlineVoiceRoutingPolicy
• Set-CsOnlineVoiceRoutingPolicy

Use the Below PowerShell Code Based On Your Region

5. Tenant Dial Plans & Normalization Rules

Microsoft recently added a section to the Teams Admin Center (TAC) that allows you to create tenant dial plans and normalization rules.  Feel free to use the TAC to configure the following steps, but since we are already using PowerShell to configure everything else, we will continue using it for this step too.

Normalization Rules

Normalization rules are regular expressions used to translate one number format to another number format.  For example, you can translate a 4-digit extension number like 1234 to a 10-digit E.164 formatted phone number.

Evolve IP uses Cisco BroadWorks for all voice features, and this includes feature codes using star "*" and pound "#".  Cisco BroadWorks also has its own means of translating and routing N-digit extension numbers.  This makes configuring Microsoft's back-end voice infrastructure very easy.  All we need to do is send any number, no matter the length or the feature code to BroadWorks for interpretation.  If the number or feature code dialed is not supported, BroadWorks will let the user know.

• Get-CsVoiceNormalizationRule
• New-CsVoiceNormalizationRule

• Set-CsVoiceNormalizationRule

• Remove-CsVoiceNormalizationRule

Get-CsVoiceNormalizationRule US | FT Name,Priority,Pattern,Translation,Description -auto
Get-CsVoiceNormalizationRule USNL | FT Name,Priority,Pattern,Translation,Description -auto

Tenant Dial Plans

Tenant Dial Plans are used to store the normalization rules.  You can use the existing Global Tenant Dial Plan, which will be applied to all users in your organization, or you can create one or more custom Tenant Dial Plans and apply them to individual users.  Since we are using the Evolve IP BroadWorks environment to handle number translations, we don't want any of Microsoft's default normalization rules to be applied.  Therefore, we will add some normalization rules to the Global Tenant Dial Plan, to circumvent Microsoft's default to affect any existing normalization rules and tenant dial plans, we will create a new tenant dial plan with its own normalization rules.

• Get-CsTenantDialPlan
• New-CsTenantDialPlan
• Set-CsTenantDialPlan
• Remove-CsTenantDialPlan

Use the following PowerShell command to check for existing tenant dial plans, and normalization rules:

Get-CsTenantDialPlan

Here's an example output when there's just the global tenant dial plan and no custom normalization rules.

Identity              : Global
Description           :
NormalizationRules    : {}
ExternalAccessPrefix  :
SimpleName            : DefaultTenantDialPlan
OptimizeDeviceDialing : False

If you

have normalization rules

in your global tenant dial plan, you can use the following command to output just the normalization rules.

(Get-CsTenantDialPlan -Identity Global).NormalizationRules

Create the Normalization Rules & Add Them to the Global a Custom Tenant Dial Plan

Use the following PowerShell commands to create the normalization rulesNormalization Rules and a new Tenant Dial Plan:

# Rule for feature access codes using the # symbol
$NR1 = New-CsVoiceNormalizationRule -Parent Global -Description "EIPEvolve TDRIP FAC Pound" -Pattern '^(\#\d{2})$' -Translation '$1' -Name EIPTDRFACPEvolveIPFACP -IsInternalExtension $false –InMemory

# Rule for feature access codes using the * symbol
$NR2 = New-CsVoiceNormalizationRule -Parent Global -Description "EIPEvolve TDRIP FAC Star"  -Pattern '^(\*\d{2})$' -Translation '$1' -Name EIPTDRFACSEvolveIPFACS -IsInternalExtension $false –InMemory

# Rule for extension dialing
$NR3 = New-CsVoiceNormalizationRule -Parent Global -Description "EIPEvolve TDRIP Extensions" -Pattern '^([10-9]\d{0,56})$' -Translation '$1' -Name EIPTDREXTEvolveIPEXT -IsInternalExtension $false –InMemory


# Create Adda thenew normalizationtenant rulesdial toplan theand globaladd tenantthe dialnormalization planrules
SetNew-CsTenantDialPlan -Identity GlobalEvolveIP-TenantDialPlan -NormalizationRules @{add=$NR1,$NR2,$NR3}


# View all normalization rules in the globalnew tenant dial plan
(Get-CsTenantDialPlan -Identity globalEvolveIP-TenantDialPlan).NormalizationRules

If needed, you can use the following command to clear all normalization rules from the global new tenant dial plan:

Set-CsTenantDialPlan -Identity GlobalEvolveIP-TenantDialPlan -NormalizationRules $null

Conclusion

After configuring the back-end Skype for Business Online Microsoft Teams services for direct routing, it is recommended to wait a few hours before provisioning your Teams users with direct routing.  This gives Microsoft's back end enough time to synchronize these changes across all of the services and infrastructure.

Our testing has shown that 3 hours is usually enough time to wait, but if you are unable to provision users for direct routing after 3 hours, let us know.  We can review your TDR direct routing configuration, and if needed, we can assist with opening a case with Microsoft.

Additionally, we recommend keeping the licenses assigned to the TDR routing domain user/service accounts until you are satisfied with your deployment.  If you're starting with a pilot group of users, wait until their testing is done, and then you can reassign the licenses to the users in your production group.
