Objectives
• To provide insight from the platform supplier perspective
• To share experiences we’ve seen and been a part of regarding this network scenario
• To help guide developers out of the field and into the lab…There will be no sales if there is no product

Word of the Day
Flexibility - Flex`i`bil´i`ty
1. the quality of being adaptable or variable;2. the ability to change or be changed to fit
changed circumstances3. the ease with which a system or
component can be modified for use in applications or environments other than those for which it was specifically designed

Flexibility…Let me count the ways
• Application(s) – Fixed & mobile, voice & signaling
• Size – <100 Channels to thousands
• Signaling - IP (SIP & H.323) & TDM (SS7/PRI/CAS)
• Architecture – IMS, SIP, Service Node
• Carrier-class and non-carrier-class – (I know this goes off topic, but as a developer you should be able to provide alternative architectures for an array of customers while minimizing your costs and their costs.)

App Developer Perspective
+ -SIP App Server
Low CapEx “Industry Standard”
– No media control– No TDM/H.323
Service Node
Flexibility - Multi-protocol Low OpEx – Single API, single vendor mgmt Dedicated media
– Hardware $– Hairpin increases OpEx
Multi-function Platform
Low CapEx & OpEx + Flexibility Fast to (new) market(s)No Hairpin of traffic
– Proprietary API

Conclusion
• For developers, there is no uniform or ideal architecture being adopted across the board by service providers, which therefore requires insight and innovation on your part
• Multi-function platforms can offer substantial benefits to service providers but ONLY if they truly meet the needs of the carrier
• As an app developer, your primary concern should be defining and exceeding your customer(s) needs while differentiating yourself and minimizing YOUR costs
