We just make cards and drivers!
• 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: System agnostic

Open Source and Commercial code
Here is a controversial statement:
There is no intrinsic difference between open and closed source code

Best of Breed:• Particularly in telephony, applications are modular• So choose the best of breed for each module• Don’t send a boy to do a man’s job

As the system has matured, The Contact center needed to grow:• Better scalability, better reliability
– Zaptel is an amazing piece of work, but was never designed for large installations
– Needs an upgrade path from E1 to SS7
• Proactive Rather than Reactive– Reach out to customers proactively
(phone, email, etc.)– Not just telemarketing– Requires Call Progress Analysis

Zaptel replacement for Scalability and Reliability
• NetBorder Express SIP gateway instead of zaptel• High performance TDM gateway• A single gateway machine can handle 4 x A108
cards = 32 E1s = 960 voice channels.• Solid commercial ISDN PRI and SIP stack, soon
to support SS7, analog, BRI…• Growth path to add other helper modules

Call Scenario:• VICIdial initiates
outbound call• Asterisk dials out to
NetBorder• NetBorder reinitiates the
call while attaching its own internal CPA resource
• Once NetBorder CPA result is known, VICIdial assigns the call to an agent if the CPA result is ‘Human’

Agent Bridge
• Regular phone looks like a SIP phone to Call Center Applications
• Inherent QoS with PSTN• No need for costly equipment to maintain at
Remote Agent site• Ease of integration (SIP, no APIs)• Security guaranteed by PSTN

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
