Open Source VS Proprietary: Choosing Best of Breed

Mixing Open Source and Proprietary
Proprietary software has dominated spending budgets
Open Source software has become interesting as applications expand
Proprietary now competes with Open Source
telecom has embraced and enabled Open Source applications to flourish.

As a Hardware Manufacturer….
Open Source is important to us
Proprietary code is important to us
But mostly our customer’s well-being is important to us
We have a unique perspective: OS and Application agnostic

Best of Breed:
Particularly in telephony, applications are modular
So choose the best of breed for each module
Send a boy to do a man’s job

PC Server How does it carry the load?
TDM load
Transcoding load
Voice quality load
Call switching

Offload Heavy Lifting to Hardware Transcoding Call Switching Echo Cancellation PSTN Access Open Source VS Proprietary: Choosing Best of Breed

HMP- Host Media Processing
HMP is the movement away from proprietary expensive hardware
To promote scalability we will continue to rely on DSP’s in high volume call scenarios for voice quality and compression
DSP’s must be low cost, standards based and performance based (programmable)

Better left to Proprietary
Signaling
Transcoding
Echo cancellation

Signaling / Homologation
SIP, SS7, PRI/BRI, analog
When connecting to a carrier, signaling certification is frequently required.
Certification/conformance testing is expensive and time consuming
Why would I spend time and resources to certify, then provide these certifications gratis

Open Source Revenue Models
Freeware VS Payware
Charge for support and implementation
99.9% of open source is 90% complete which spurs contract development services

Proprietary Revenue Model
Charge for applications
Charge for API’s
Charge for support
Charge for updates and maintenance
Charge for development

Summary
Use what makes most sense, do not be an Open Source bigot
Don’t be a commercial code bigot either!
Make full use of the nature of telephony applications to make changes in a modular way as your needs and business changes
