• For more prerequisite details, see Microsoft's document for Plan Direct Routing.

...

Direct Routing requires a custom domain for each Office 365 tenant. For more information, click here.

...

The domain names for SBCs must be in the list of domain names registered in the "Domains" section under Settings of the Microsoft 365 admin center menu. The domain of a tenant must be activated and have a Healthy status. Go to the admin dashboard to add domains not already created and verified.

• For more information about Microsoft SBC domain names, click here.

...

• Table note The IPs and domain names in this document are examples.

...

• To learn more about SBC certificates, refer to this Microsoft documentation.

...

1. Connect the SBC with phone system and validate connection

Using the Microsoft Teams admin center

To add the Peeredge SBC to Direct Routing:

...

• Create the user in your on-premise Active Directory and sync the user to the cloud.

• Create the user directly in the Tenant using the Microsoft 365 admin center, Microsoft 365 Azure Active Directory Portal, or via PowerShell.

Must be configured for Teams Only mode

...

Must be homed online, enabled for enterprise voice, and assigned a phone number

Using the Microsoft Teams admin center:

1. Go to Users -> Manage users.

2. Select a user.

3. Under Account General information, select Edit.

4. Under Assign phone number, click the Phone number type drop-down menu and select Direct Routing.

5. Enter an assigned phone number and a phone number extension, if applicable.

6. Click Apply.

...

3. Configure call routing

Call routing has the following elements:

Call routing policy

Also called a Voice Routing policy. A container for PSTN usages, which can be assigned to a user or to multiple users. Sample Call routing policy names include:

• US Only

• US Global

• Germany Only

• Germany Global

• Internal

PSTN usages

A container for voice routes and PSTN usages, which can be shared in different voice routing policies. Sample PSTN usage names include:

• US-Emergency

• US-LD

• US-INTL

• Company-Internal

Voice routes

A number pattern and set of online PSTN gateways for calls where the calling number matches the pattern. In the examples below, the Internal voice routes represent routes to company-managed third-party PBXs used by employees that have not yet migrated to MS Teams. Sample Voice route names and their associated dialed number patterninclude:

• US Emergency ^933$

• US LD e164 ^+1[2-9]\d{2}[2-9]\d{6}$

• US INTL e164 ^+[2-9]\d+$

• Reston Internal ^+170355512\d{2}$

• Chicago Internal ^+13125556[43]\d{2}$

Online PSTN gateway

This is a pointer to the Peeredge SBC that also stores the configuration which is applied when a call is placed through the SBC, such as forward P-Asserted-Identity (PAI) or Preferred Codecs. The pointer can be added to voice routes.

Two examples (from Microsoft) of voice routing policies in a call flow.

...

Create the PTSN usages

In the following example, we create four PSTN usage records. We suggest admins use easy-to-understand names representing the types of calls a user is allowed to dial. Using the Microsoft Teams admin center:

1. Go to Voice -> Direct Routing.

2. Select Manage PSTN usage records in the top right corner of the page.

3. Click + Add and enter the name of the PSTN usage record.

4. Repeat step 3 to add more records.

5. Click Apply to finish.

...

In the following example, we create four voice routes. The dial number patterns are in the form of a regular expression (regex). You can validate your regex patterns.
Using the Microsoft Teams admin center:

1. Go to Voice -> Direct Routing.

2. Click the Voice routes button.

3. Click the Add button.

4. Add the name Non-Emergency Test in the voice route in the Add a name for your voice route field.

5. Make sure the Priority is 1.

6. Make sure the Dialed number pattern is ^933$.

7. Click the Add SBCs button and select your Peeredge SBCs and then click Apply.

8. Click the ADD PSTN usage button and select the US-Emergency PSTN Usage and then click Apply.

9. Click Save.

10. Repeat steps 3 – 9 for any other voice routes using an appropriate priority and PSTN Usage. When overlapping dialed number patterns exist, give the more specific pattern higher priority.

...

Create the voice routing policy

Using the Microsoft Teams admin center:

1. Go to Voice -> Voice routing policies.

2. Click the + Add button.

3. Add the policy name in the Add a name for your voice routing policy field.

4. Add an appropriate description.

5. Add one or more PSTN usages.

6. Click Save.

7. Repeat steps 2 – 6 for each voice routing policy.

...

Assign the voice routing policy to a user

Using the Microsoft Teams admin center:

1. Go to Voice -> Voice routing policies.

2. Highlight the voice policy you want to assign.

3. Click the Assign button.

4. In the Manage user search box, search for the user and click add when found.

5. Click Apply.

...

The example below shows how to add a typical US dial plan.

Using the Microsoft Teams admin center:

1. Go to Voice -> Dial plans.

2. Click the +Add button to add a Tenant dial plan.

3. Add the dial plan name (US DP) in the Add a name for your dial plan field.

4. Add an appropriate description (Tenant User Dial plan for US-based users).

5. Add an External dialing prefix (8). Legacy PBX was often configured with 8 or 9 as an external dialing prefix to route the call to an external line.

6. Set Optimized device dialing to ON if you configured an External dialing prefix.

7. Click the Add button under Normalization rules to open the Add new rule pane.

8. Enter a rule name (Non-Emergency Test Call) in the Name field.

9. Add an appropriate description.

10. Select an appropriate Rule creation mode (Advanced).

11. Enter a dial pattern to match (^(911)$) in the If condition.

12. Enter the translation/number manipulation ($1) in the Then do this field.

13. Optionally, enter a number in the test this rule field to validate the rule. A validated test results in, "The translated number is an E.164 phone number."

14. Click Save.

15. Repeat steps 7 – 14 to add Normalization rules.

16. Click Save.

A Rate deck is a table that shows a call destination and cost to complete. Rate decks can be assigned to any type of trunk group. There are five types of rate decks.

For US-Based Customers

An Origination Customer Trunk Group is typically assigned a US & Canada DID rate deck and a US & Canada Toll-Free rate deck.

...
