Microsoft Lync Server 2010: Presenting phone numbers to contacts

JoostAt the moment I am involved in several Microsoft Lync 2010 implementations. During these implementations I got a lot of questions which weren’t addressed during the courses I followed for this product. Some of the questions are relatively simple to answer, some aren’t. In order to answer the most common questions, I will post several blogs related to these questions. This first blog was a question of colleague. This colleague is using federation a lot during his normal work. He asked me how he could ‘hide’ certain contact details as these should be only available for the internal organization. In order to answer the question above there are two possible options you have in Lync 2010 (but also in OCS and Lync 2013). First we have the ‘Phones’ option and second there is the privacy relationship option. I will explain both of them.

When entering the Lync Options Menu (press the wheel and then choose for options), there are a lot of tabs visible. One of them is called ‘Phones’. From this tab the user is able to add phone numbers, when they are not provisioned from other sources. In most of the cases the mobile phone will be filled in, as this phone number is supplied through the Active Directory. Other phone numbers can be entered by pressing the correct button and supply the phone number. Now behind the number on the options menu, there is a checkbox displayed. This checkbox enables to user to choose whether or not the phone number is included in the contact card. When checking or unchecking this checkbox an notification will appear. The text on this information box is quite important. As the text states that:

“Phone numbers you publish will be available to your contacts depending on their access level. Phone numbers supplied by your corporate address book are available to people within your organization regardless of their access level”.

This text states two things. First of all, you are able to choose whether or not phone numbers will be displayed based on the access level (also known as privacy relationship, see below). So by unchecking the checkbox next to a number that you have supplied manually, the phone number will not be displayed on the contact card (not even for colleagues). Second whenever information is published through the Active Directory (or corporate address book) the contact information is always visible. As already mentioned before some information is supplied through AD. As this information is accessible through other applications as well (SharePoint, Outlook etc.) this information will be always available for colleagues.

Besides the earlier mentioned options the user is able to define a privacy relationship for each contact. By clicking with the right mouse button on a contact in the contact list a menu appears. In the menu an option called “Change Privacy Relationship” is available. When hovering over this option, several privacy relationships and their descriptions are shown (see picture on the right).

As there are 5 relationship statuses available the correct one is always available. By default all contacts are assigned with a certain status. Whenever adding an internal colleague (internal contact) the privacy relationship ‘Colleague’ is added. Whenever an external contact is added,  the privacy relationship external contact is also added to the contact. Whenever the contact has too much (or maybe too little) information the relationship with the contact can be changed. In order to change the relationship, just click another relationship, and the status is changed.

Using this settings enables the user to define which contacts sees which information. However there are some another advantages in dividing contacts with these kinds of relationships:

  1. Do not disturb. When you set your presence status to ‘Do not Disturb’ normally no notifications will be shown. However, when a contact is set with the relationship type ‘Workgroup’ the contact is considered as important. This means that you will receive messages from this contact whenever he or she is setting up a conversation (whether it is instant messaging or audio/video).
  2. Sorting of contact list. When all contacts are set with certain privacy relationships, a special view is available. The default view of Lync 2010 client is based on the contacts list you created. When looking at the bar above the contact list, the text ‘Relationship’ is shown. Whenever pressing this link the contact list will be sorted to the privacy relationships. For each privacy relationship a group is shown, with all users assigned to that privacy relationship.

In the table below an overview of all information that is shown to contacts with certain privacy relationships is added.
