 Learning Objectives

Why this seminar?

While the VoIP (Voice over IP) hype for the consumer market is in full swing (e.g. look at all the hype about the acquisition of Skype by eBay), we're post-hype in the corporate market. Many companies and public institutions are announcing or implementing large-scale migrations, and for new greenfield situations, Voice over IP is a no-brainer. The advantages of scalability, usage of one single network for Voice and Data and easier maintenance outweigh any remaining doubt about sound quality, service level and robustness.

However, also for companies with an existing telephony infrastructure, IP telephony is an option. Growth in work force, relocation, setting up new branches, all of this can be the trigger to implement a mixed VoIP-PABX solution.
And last but not least: the convergence of Voice and Data enables new functionality: flexible solutions for mobile workers, "intelligent" phones (as a device or software-based) that are capable of handling metadata and application logic, and the integration of phone calls as just another data-input stream for CRM or ERP-like applications.

But decisions about corporate telephony aren't taken overnight: users do not accept the slightest glitch when it's about telephony (compare this with software applications, where failures seem to be taken for granted!). Vendor choice will determine your strategy for the coming years, and, as always with young technologies, there's the risk of expensive proprietary systems lacking long-term prospects.

This is why we have set up a vendor-independent seminar that includes a thorough overview of the technology and its opportunities, and considerations on product and strategic choices. A real-life case-study will illustrate the issues at stake.

What questions will be answered during this seminar ?

  • What are the advantages of VoIP over traditional telephony ? What are the risks and drawbacks?
  • What is the history of the players in this market, what are their strengths and weaknesses and their future strategy?
  • Do I have to choose for a pure VoIP solution or a hybrid VoIP/PABX?
  • What additional functionality do I get with VoIP? What is the extra cost and the effort required to implement it?
  • How do I calculate the ROI of a migration? How to quantify the extra functionality offered by VoIP?
  • What about external telephony: what are the consequences after switching to VoIP internally?

Who should attend this seminar ?

  • IT managers who want to be prepared for strategic choices in Voice and Data integration.
  • Telecom managers searching for a vendor-independent overview of internal VoIP solutions
  • Application developers searching for an overview of VoIP technology and possible applications built on IP telephony
