SAC at CTIA from Omar Chohan shares

how its market share and geographic

presence has increased in quality,

quantity and revenue partly because of

using DIDX for virtual phone numbers

over SIP. Listeners should stay tuned

through the end of the interview to

hear the exciting way that SAC is

using Regus virtual offices with

DIDX.net virtual phone number

services.

SAC has also been able to reduce much

of its overhead costs because of SIP

trunking and international presence

provided by its association with

DIDX.net. SACS has grown in revenue

over 30 million since the last time we

interviewed Mr. Chohan on podcast in

2007.

They initially chose the unified

communications service of Cisco Call

Manager for IM presence, voice,

voicemail, call routing, auto

attendant, and call gateway. A problem

with the Cisco solution is its

inherent architecture, great for

traditional markets but not emerging

markets that do not have the bandwidth

capacity to handle the overhead, etc.
Next SAC moved to the Microsoft OCR2

platform, leaner and more cost-

effective. Their entire back-end is

virtualized with virtual ware and

Citrix and deployed using SIP.

Omar talks about the changes SAC has

made in migration from the Cisco to

the Microsoft solution in the area of

mobile integration. SAC created a

workaround from the Cisco's MVS

(mobile voice suite) to Microsoft's

Windows' voice platform to integrate

the company's Blackberry cell phones

to the IP PBX.

We discuss the types of companies who

are in the best position to use

DIDX.net for buying international and

USA phone numbers. Omar says small

businesses should find out which

telephony service providers are DI
