• Making the right platform choice can make your
  life as a developer much more enjoyable

Introduction

• Who am I?
• Louis R. Marascio, former CTO of Metreos
  Corporation
• Metreos was acquired by Cisco Systems in June
  2006
• For the past 6 years I have been building a
  development platform, tools, and applications for
  large Cisco IP Communications customers
• In this session I hope to share with you
  knowledge learned through painful trial and error
  in the real world

Different Types of Platforms

• VoiceXML (read IVR)
• J2EE SIP (or your protocol of choice)
• IP Communications Application Environments

5
VoiceXML PROS CONS

• PROS
• Standard, well defined, and popular for IVR
  definition
• Good for building IVR oriented applications
• CONS
• But what happens when you just want to push some
  text and audio to an IP phone without a call

J2EE SIP PROS and CONS

• PROS
• Familiar development environment
• Relatively straightforward call control protocol
• CONS
• But what happens when you need to process or
  manipulate media

IP Communications Application Environments PROS
and CONS

• PROS
• Great for building any type of IP communications
  application
• Extensible to (at a minimum) the phone system
  that it is tightly integrated with
• CONS
• New, less familiar development environment

Key Ingredients

• Telephony must be made easy
• Abstract that nasty call control
• Media processing should be built in
• A VoIP application without media is like a
• Dial tone should be ensured and preserved
• The developer who breaks dial tone is going to
  have a very bad day
• Extensibility and a non-voice centric view of the
  world
