Microsoft Lync 2010 Server Address Book Normalization

As in Precious version of Clients , any phone Numbers stored in AD “Active Directory” phone Attributes using the E.164 formats will be displayed by Lync Client on both Contact Call menu , and contact card Details.

 

For example the Pattern +97112345678901 is populated on the AD and will appear on the Lync Call menu and contact card.

 

but if the Pattern is 0097112345678901 or 97112345678901, Lync server will fail to normalize it into E.164 and so , will not appear on the Lync Contact Card or call menu.

 

 

In order to display Number formats that not E.164 , Lync Server will need to be manually configured to properly normalize those numbers.

 

Configuring Address Book Normalization

By default normalization is already enabled in Lync Server which can be verified by the viewing the Lync Server’s current Address Book configuration.

 

to Verify this :

Open Lync Server Managment Shell (using account with Admin Previliges ) , and write the following Command:

Get-CsAddressBookConfiguration

 

 

 

 

the UseNormalizationRules Value should be Already Set to “True”.

 

Now locate the Lync Server’s shared directory which was configured during the initial server deployment.  The file server FQDN and share name can be identified in the Topology Builder under File Stores.

 

Browse to the share directory on the server and locate the ABFiles subdirectory.

\\LyncFEserver\LyncShare\1-WebServices-1\ABFiles

 

Create a new text file named Company_Phone_Number_Normalization_Rules.txt in the ABFiles directory.  This normalization rules file must be stored in this location and not down a few directories where the actual address book files are stored as it was in Lync server.

 

Edit the file with Notepad and enter the following example normalization and translation patterns.  This rule will apply to  the users configured with phone numbers in this standard 14-digit format: 0097112345678901.  (The first three lines are commented out and are not required in the text file.)

 

this Normalization rule will remove the First two Digits (00) and Add (+) instead. to convert it to the E.164 formats.

 

##

## Normalization rule to convert the 14-digits number starting with (00) to E.164 format

##

^00(\d{12})$

+$1

 

Save the changes to the Txt File and close it.

Now you will need to Update the address book for Lync Server for the new Configuration to take place,

 

this might take up to 5 minutes to happen.

 

To Update the AddressBook use the following Command-line in the Lync Management Shell:

 

> Update-CsAddressBook

 

after 5 minutes sing out and sing in again to your Lync Client and the Phone numbers will be appearing in Lync Dial menu.

Certificate Chain is Invalid / Problem Deploying Lync Server

Howdy,

 

Sometimes While Deploying Microsoft Lync Server, when it comes to Requesting and Assigning Certificate for the Lync Services It will fail with the following Error (Although it should not fail because your Internal CA root certificate should be installed automatically once the server is joined to the domain):

 

A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. (Exception from HRESULT: 0x800B0109)

 

To solve this Error you will need to Download the Certificate chain from your Certificate Authority , and install it in the Lync FE .
