Skype for Business Address Book normalisation rules

In the past Lync used txt files Company_Phone_Number_Normalization_Rules.txt to manage normalisation rules, with SFBit is now powershell Get-CsAddressBookNormalizationRule, etc.

By default it contains already some rules, but if you need to modify you can.

Here is a test tool that will show existing rules and will allow to test with a specific test number:

One thing remains unclear - the tool and all articles that I could find says that SFB will automatically strip spaces and other symboles like dashes from the phones number. However, I have an example where it does not work - when number is typed in contact lookup in SFB client the string must match exactly the string in AD phone field, otherwise the contact is not proposed. For the moment I do not know why. In another installation it work ok. It looks like something related to either client version  or method (web search only) or client  or GPO policy - had no time to analyse further.

SFB does not deliver a call due to a duplicate

We had a case where, a duplicate prevented call being delivered to Poycom VVX. As you can imagine we spent some time to take logs and understand the issue. but it is simply not visible on that level. When we got traces from the SBA mediation server, it was clear that call is rejected by SFB due to a duplicate.

ms-diagnostics: 4002;reason="Multiple users associated with the source phone number";

Checking in powershell revealed nothing, however in SQL resources table on SBA we discovered records that were deleted, but never left SQL.

Here is how to check this: http://lyncinsider.com/skype-for-business/sql-active-directory-mismatch-prevents-skype4b-user-login/    and http://lynclead.com/?p=324
