| Session Border Control in IMS |
An analysis of the requirements for Session Border Control in IMS networks
By Jonathan Cumming - Director of VoIP Product Management
There is a lot of controversy and press coverage over both the role of Session Border Controllers (SBC's) and the design of the IP-Multimedia Subsystem (IMS). In this environment it is difficult to determine what are the real issues for each technology, let alone how they need to work together.
This white paper is aimed at equipment manufacturers looking at building SBC functionality into their product range to target the IMS market, and carriers and consultants looking to understand how an SBC fits into an IMS network. More >>>

| The question of return on investment (ROI) of VoIP |
Mike Matthews, Head of Product Marketing, Aculab
What does a developer need to consider before creating IP telephony solutions while keeping the total cost of an enterprise solution in mind?
 The first consideration is the customer that the developer is targeting their application for. Depending on the company culture and current communications infrastructure, different aspects of the total solution become more critical - majoring on either a feature or a cost basis. A developer needs to ask questions and tease out the answers from their prospective marketplace, as the responses to these questions will affect not only the cost and features to be implemented but also the best enabling technology option. This article works through a number of these qualification questions and proposes the best way forward — always keeping an eye on cost and ROI. Read the full whitepaper here (PDF)>>>
