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
