PSTN Numbering Plan
Pattern Destination Description
911 PSTN phone Emergency number
XXX XXXX PSTN phone Any 7-digit number for PSTN local calls
1 XXX XXX XXXX PSTN phone 1 followed by any 10-digit number for PSTN national calls 011<as many as 14
digits> PSTN phone 011 followed by as many as 14 digits for PSTN international calls
1 800 XXX XXXX PSTN phone 1800 followed by 7 digits for PSTN toll free calls 1 900 XXX XXXX PSTN phone 1900 followed by 7 digits for PSTN premium calls
Note When dialing from the Cisco Unified Communications Manager cluster to the PSTN, a PSTN access code 9 must be prefixed to all PSTN numbers. This PSTN access code should not be sent to the PSTN.
Task 1: Configure a Route Plan That Uses Both Gateways and Includes Two Route Groups, a Route List, and Route Pattern
In this task, you will configure routing to the PSTN, using both configured gateways. You will configure gateway HQ2-x to be preferred over gateway HQ-x.
Activity Procedure
Complete these steps:
Create Two Route Groups in Cisco Unified Communications Manager
Step 1 Navigate to Call Routing > Route/Hunt > Route Group and click Add New.
Step 2 Enter the following parameter in the Route Group Information window:
Route Group Name: RG_MGCP_GW
Step 3 In the Available Devices field, choose the HQ-x MGCP gateway identifier
(S0/SU0/DS1-0@HQ-x) and click Add to Route Group to add the HQ-x gateway.
Step 4 Click Save.
Step 5 Click Add New to add a second Route Group.
Step 6 Enter the following parameter in the Route Group Information window:
Route Group Name: RG_H323_GW
Step 7 In the Available Devices field, choose the HQ2-x gateway identifier and click Add to Route Group to add the HQ2-x (10.x.1.102) gateway.
Step 8 Click Save.
Create a Route List in Cisco Unified Communications Manager
Step 9 Navigate to Call Routing > Route/Hunt > Route List, and click Add New.
Step 10 Enter the following parameters in the Route List Configuration window:
Name: RL_HQ_GWs
Description: HQ PSTN Gateways
Cisco Unified Communications Manager Group: Default
Step 11 Click Save.
Step 12 In the updated Route List Configuration page, click Add Route Group in the Route List Member Information pane and choose the RG_MGCP_GW route group.
Step 13 Choose Discard Digits Instruction NANP:PreDot as Called Party Transformation for the RG_MGCP_GW.
Step 14 Click Save. Click OK in the pop-up window.
Step 15 Repeat Steps 12 and 14 for the RG_H323_GW route group, but do not choose any entry in the Discard Digit Instructions for the route group.
Note Typically the PSTN access code is stripped at the H.323 gateway using Cisco IOS digit manipulation features. Therefore, you have to send PSTN numbers with PSTN access code 9 to the Cisco IOS gateway.
Step 16 Change the order of the route groups in the route list so that route group RG_H323_GW is listed before route group RG_MGCP_GW.
Step 17 Click Save. Click OK in the pop-up window.
Create a Route Pattern in Cisco Unified Communications Manager
Step 18 Go to Call Routing > Route/Hunt > Route Pattern, and click Add New.
Step 19 In the Route Pattern Configuration window, enter the following parameters:
Route Pattern: 9.!#
Description: PSTN Access with #
Gateway/Route List: RL_HQ_GWs
Discard Digits: <None>
Note Digit manipulation is performed at the route-group level.
Step 20 Click Save. You are notified by a pop-up window that the authorization code will not be activated. Click OK.
Step 21 You are notified by another pop-up window that changes will reset the gateway.
Click OK.
Step 22 Repeat the Steps 16 through 19 to create another route pattern, but enter 9.! as the Route Pattern parameter and enter PSTN Access with Interdigit Timeout as the Description.
Note You can use the Copy icon to create a copy of the existing route pattern, which you can modify as required.
Activity Verification
You have completed this task when you attain these results:
From a Cisco IP phone in your pod, you can successfully reach a PSTN number using the prefix code 9 (for example, 9-555-7890). When dialing the number, you can either wait for the interdigit timeout to expire or press the # key to instruct Cisco Unified Communications Manager to stop digit collection. Verify that the call is received at PSTN-Phone-x and accept the call at the PSTN phone.
Task 2 (Optional): Enable Cisco Unified Communications Manager Dialed Number Analyzer and Use It for Dial Plan Verification
In this task, you will install Cisco Unified Communications Manager Dialed Number Analyzer and use it to verify that gateway HQ2-x is preferred over gateway HQ-x for calls sent to the PSTN.
Activity Procedure
Complete these steps:
Activate Cisco Unified Communications Manager Dialed Number Analyzer Service
Step 1 Access Cisco Unified Serviceability, and go to Tools > Service Activation. Choose the publisher server 10.x.1.1 from the Server drop-down list. Click Go.
Note The Cisco Unified Communications Manager Dialed Number Analyzer service must be activated on the publisher server. The service can also be activated on the subscriber server, in case the Cisco Unified Communications Manager Dialed Number Analyzer service on the publisher is unavailable. Activating the service on the subscriber only does not enable the Cisco Unified Communications Manager Dialed Number Analyzer web page.
Step 2 Choose Cisco Dialed Number Analyzer from the CM Services list, and click Save.
Note If the service is already activated, the Activation Status displays as Activated.
Step 3 The service is activated and the Activation Status column displays the status as Activated.
Access Cisco Unified Communications Manager Dialed Number Analyzer
Step 4 To access Cisco Unified Communications Manager Dialed Number Analyzer, go to Tools > Dial Number Analyzer in Cisco Unified Serviceability.
Step 5 A pop-up window appears. If you are prompted to enter the username, enter cucmadmin as the user ID and cucmpass1 for password. Click OK. You are now logged in to Cisco Unified Communications Manager Dialed Number Analyzer.
Note You can also use the URL https://10.x.1.1/dna to access Cisco Unified Communications Manager Dialed Number Analyzer. You do not need to access it from Cisco Unified Serviceability.
Perform a Simple Analysis by Using the Analyzer Window
Step 6 Navigate to Analysis > Analyzer.
Step 7 Enter the calling-party digits 2002 in the Calling Party field. By default, 1000 displays in this field.
Step 8 Enter the digits 9911 (or any other valid PSTN number starting with 9), in the Dialed Digits field.
Step 9 Click Do Analysis to start the analysis. Cisco Unified Communications Manager Dialed Number Analyzer analyzes the dialed digits and displays the results in a new window, the DNA Analysis Output window.
Step 10 In the DNA Analysis Output window, click Expand All. Under Call Flow, at the end of the Route List output section, the gateways are listed in the order in which they are used to route the call.
Activity Verification
You have completed this task when you attain these results:
In Tools > Control Center—Feature Services, the Cisco Unified Communications Manager Dialed Number Analyzer service is activated and started.
From a Cisco IP phone in your pod, you can successfully place a call to the PSTN phone by dialing a valid PSTN number (starting with prefix digit 9).
You performed call analysis by using Cisco Unified Communications Manager Dialed Number Analyzer. The output shows that gateway HQ2-x is preferred for calls to the PSTN.
Note Cisco Unified Communications Manager Dialed Number Analyzer is not aware that the H.323 gateway (HQ2-x) is not running and therefore considers the primary path only.
However, because you were able to place the call to the PSTN (using the backup gateway HQ-x), you successfully verified your route list and route group configuration.
Cleanup
Remove the PreDot digit stripping instruction at the Route List for the RG_MGCP_GW Route Group.
Step 1 Navigate to Call Routing > Route/Hunt > Route List and click Find.
Step 2 Choose the RL_HQ_GWs route list.
Step 3 Click the RG_MGCP_GW link in the Route List Details field.
Step 4 Set the Discard Digits Instruction to <None>.
Step 5 Click Save, then OK, and then Reset.
