This article describes the steps necessary to configure the SBC Edge (SBC) to fork calls using User attributes stored in Active Directory by employing the SBC's Transformation and Call Forking features.
In this example we use a PSTN - SBC - Lync/SBA environment, and we want to route all calls from PSTN to Lync clients to a Lync user, and we want them forked to the same Lync user's mobile and IP phone numbers using attributes from the user's AD record.

A PBX phone 6222 dials the Lync/SBA user's extension number 1005, resulting in the call landing on the inbound ISDN Signaling Group on the SBC. The call is then routed using the relevant Call Route Table triggering the relevant sequence of events:
Before you begin, you'll need to verify the following:
Before you begin, make sure the SBC is configured and integrated with Lync/SBA as described in Call Routing Based on Active Directory User Attributes. In addition to this, verify the SBC Active Directory settings:

In this section, we provide a step-by-step configuration walk-through enabling the use of Call Forking on the SBC:
For details on field configuration, refer to Creating and Modifying Entries to Transformation Tables.
We will need three Transformation Tables created as shown below:
Configure the "Calling Address/Number" and "Called Address/Number" translations..
msRTCSIP-Line
).Configure the "User Value" translation to another AD attribute format "ipPhone".
msRTCSIP-Line
)Configure the "User Value" translation to another AD attribute format "mobile".
We create three entries in a Call Route used for ISDN to Lync calls. For details on field configuration, refer to Managing Call Routing Tables.
ISDN to Lync/SBA client route entry
Configure Fork Call as Enabled.
Select Number/Name Transformation table for ISDN to SIP.
Select the applicable Destination Signaling Group.
ISDN to Lync/SBA client's ipPhone route entry
Configure Fork Call as Enabled.
Select Number/Name Transformation Table for ipPhone.
Select the applicable Destination Signaling Group.
ISDN to Lync/SBA client's mobile device route entry
Configure Fork Call as Disabled.
Select Number/Name Transformation Table for To Mobile.
Select the applicable Destination Signaling Group.
The ISDN signaling group for inbound calls must be configured to use the relevant Call Routing Table (configured in the previous section):
