SFB Server Edge for Hybrid PSTN voice

Regular Visitor

Hi Folks,


I was going through hybrid voice deployment for PSTN calling.

In this TechNet page, It clearly mentioned that we need SFB edge for making PSTN calling through an On-Prem PSTN gateway on a Hybrid configuration.

Is it possible to add an SFB Edge on a Lync 2013 On-Prem Edge? Is it just like adding a Lync 2013 edge?

What would be the licensing requirements for SFB edge and from where we can download the installer (Trial installer is enough?)

As per the documentation we would require to have a on-premises Lync 2013 Edge or Skype for Business 2015 Edge Server. We would require to install the same in the topoloy file.


If you have deployed the Lync 2013 On-premises configuration we need to use the same set-up file for deploying the Lync 2013 Edge Server. You can use the below article which gives the detalied description on how to deploy the Lync Server 2013



In addition to this you would require to set up directory synchronization and pruchase the Cloud PBX Licenses.
