Hello all,

we updated the client to Skype For Business and in this client don't see 5-digit numbers in contact cards.

We have a lync 2010 server,  
For users we set Work phones as internal 5-digit number
On server we have a file Company_Phone_Number_Normalization_Rules.txt with the text:
(\d{5})
$1

Everything is ok with lync 2010 client and lync 2013, but when we updated to SkypeForBusiness client those numbers are gone.

Are there in solution/fixes for that?

thank you
Best Regards,
Anton

Hi,

From your description above, did you mean after update to the latest version for Lync Server 2010, and update to Skype For Business, only SFB client couldn't view the phone number but Lync 2010 and Lync 2013 client still could view the phone number as normally?

If it is the case, as Lync 2010 and Lync 2013 could view the number, it could be the client difference between Lync 2010/Lync 2013 and SFB client. 

Please run the following Lync Server command Set-CsAddressBookConfiguration and set the value of the parameter UsenormalizationRules to False. Then test the issue again.

Best Regards,
