Throughout this series I will be making a set of assumptions based on an ideal topology in a greenfield deployment. Before we start jumping in and configuring the SBC, we must first understand how the functions on the SBC work. This article is the first in a series, that provides step by step guides on configuring the Sonus SBC with Skype for Business in order to provide PSTN connectivity for your SfB users. However, if you have landed on this post then there is a good chance that you have already decided to use Sonus SBCs and got your hands on either the 1000, or 2000 SBC model. This article does not go into detail over which device is best for you, that is down to your own informed choice. However, here in the UK, it seems that Sonus Session Border Controllers (SBCs) are the number one, preferred choice over the other competitors. There are a number of vendors out there that provide SIP connectivity hardware for Skype for Business. If you have deployed Skype for Business and now your company wants to introduce enterprise voice functionality for users, you may well find yourself looking for supported telephony equipment.
