What is SEFA Util

SEFAUtil (secondary extension feature activation) is a command-line tool that enables Skype for Business Server 2015 communications software administrators and helpdesk agents to configure delegate-ringing, call-forwarding, simultaneous ringing, team-call settings and group call pickup on behalf of a Skype for Business Server 2015 user. The tool also allows administrators to query the call-routing settings that are published for a particular user.The SEFAUtil tool allows the administrator to enable/disable/modify call forwarding or simultaneously ringing on behalf of the user. The administrator can specify the target (in the form of a SIP URI) or use a target that has already been published by the user. This tool also allows administrators to add or remove delegates or team-call group members on behalf of the user.This tool is built on Microsoft Unified Communications Managed API (UCMA) 3.0 and requires that administrators create a trusted application in the Central Management store for SEFAUtil.

Configure Trusted Application Pool

Login to the Front End Server and open Skype for Business Management Shell. We need to create a Trusted Application Pool.

In my lab i’m using a Standard Edition Server so i’ll create a pool with one server:

    New-CsTrustedApplicationPool -Identity skypefe01.skypedev.nl -Registrar skypefe01.skypedev.nl

We also must define a Trusted Application (If required, a different port can be used**)**

    New-CsTrustedApplication -ApplicationId sefautil -TrustedApplicationPoolFqdn skypefe01.skypedev.nl -Port 7488

Enable the Topology changes:

    Enable-CsTopology

To Verify your settings:

    Get-CsTrustedApplication

Install Resource Kit

Since there are some problem’s installing the Skype for Business Resource Kit i’ve made a workaround to deploy the Resource Kit for SEFAUtil.

Now first let’s download the Lync Server 2013 Resource Kit (Click Here).

Install the Resource Kit and only change the location:

After installing the Resource Kit is installed in “C:\Program Files\Skype for Business Server 2015\ResKit”

Next; Download the Resource Kit for Skype for Business Server 2015 (Click here)

Now use a tool like 7zip to extract the OCSReskit.msi file. In the extracted files you’ll find the file “File_sefautil.exe”. Copy the file to a temp location en rename it to “SEFAUtil.exe”. Go to the “C:\Program Files\Skype for Business Server 2015\ResKit” folder and rename “SEFAUtil.exe” to “SEFAUtil.old.exe” or something similar (Just in case you will have problems).

Now copy the the SEFAUtil.exe from the temp location to the folder.

Enjoy SEFAUtil!
