• The FQDN/IP of the Domain Controller
• What AD attribute will be used as key to retrieve records? msRTCSIP-Line, name, or mail are common AD attribute to set as the LDAP search criteria.
• What area of the Active Directory should be searched?

SBC AD Configuration

The SBC must be configured for:

...

1. Click the Settings tab in the top nagivation, then select Domain Controllersin the left-hand navigation

   borderStyle none
   Caption 0 Figure 1 Domain Controllers Image Modified

2. Enter the AD information for your network

3. Click Configurationin the left-hand navigation.

4. Configure the Active Directory Configuration as shown. Add whatever Cache Attributesyou plan to use.

   Tip
   The minimum configuration for this example document should include the attributes: msRTCSIP-Line, name, displayName, mail, telephoneNumber

2. Click Display Statisticsand verify that the AD queries are succeeding.

4. Select the Tasks tab in the top navigation and click Active Directory Cache Query. In the form, pick an AD attribute from the pulldown and supply a corresponding value.

   Note
   Queries of the msRTCSIP-Line must match precisely what appears in the Lync Line URI for the desired user, unless Normalized Cache is configured to True. If the cache is normalized, the tel: will be removed from the Lync User Line URI.

...

1. Create a transformation table with an entry to search for a msRTCSIP-Line entry that matches the called number and returns the mobile number.

2. Create a new call route table, then a call route entry to the table. In the example, the Calls to Mobile transformation table (above) is added to the call route (below).

3. Create a second transformation table with an entry to search for a msRTCSIP-Line entry that matches the called number.

4. Add a second entry to your Call Route table to send the call to the Lync Server. As before, add the transformation table above to the call route below.

5. Your call route table should look like this:

Column Info Expand If you are planning to employ AD lookups for Lync Line URI (msRTCSIP-Line), your searches will likely require additional number translations. Click here to view some common number normalizations for msRTCSIP-Line AD lookups. If you are planning to employ AD lookups for Lync Line URI (msRTCSIP-Line), your searches will likely require additional number translations. Click here to view some common number normalizations for msRTCSIP-Line AD lookups. It is often necessary to change (normalize) a number before performing an AD lookup. The vast majority of lookups require just the addition of +countrycode (i.e. +1 for the US) for a number that is already 10 digits (areacode+number). The Lync Line URI (msRTCSIP-Line) is different as it is always prepended with tel: and often postpended with ;ext=number. Since AD searches must be exact matches, the number must be corrected before the search. Below are some common normalization transformations. Tip If Normalize Cache is configured to True, the tel: will automatically be removed from msRTCSIP-Line before the SBC caches the number. Setting Normalize Cache to True is recommended.

As stated before, Online mode is not recommended.
