Voice and Data Convergence

With globally distributed workforces and the sharp increases in telecommuting, enterprises have seen their telephony networks grow more complex, entailing higher costs and sprawling administrative overhead. The converging of voice and data networks, one of the fastest growing areas of communications, provides an opportunity to address these problems. Voice over IP (VoIP) and IP Telephony (IPT), delivering voice communications via Internet Protocol in discrete packets rather than through circuit switched protocols of the public switched telephone networks, is revolutionising voice communications.

Sigma Technology's partner, Cisco, leverages existing IP networks to support voice communications across LANs and WANs, enabling businesses to connect a globally distributed workforce - from overseas sales offices to telecommuting executives - with a unified, cost-effective phone system. Together, Sigma and Cisco provide state-of-the-art IP telephony that is reliable, and easy to use and administer. Our telephony solution benefits our clients by allowing them to do the following:

• reduce costs
• simplify infrastructure
• consolidate operations

Reduce Your Costs

Cutting your long distance costs - both voice and fax - may be reason enough to implement VoIP. Moreover, the ability to share equipment and operations costs across data and voice users can improve overall network efficiency. VoIP can also create economies of scale for voice, since excess bandwidth is shareable and can be allocated where needed.

Simplify Your Infrastructure

An integrated infrastructure that supports all forms of communication delivers the following benefits:

• enables greater standardisation
• reduces the total need for equipment
• supports dynamic bandwidth optimisation
• enables fault-tolerant system design

Differences in traffic patterns between voice and data make VoIP significantly more efficient than traditional telephony. Moving your voice communications as data traffic means that voice communications benefit from network optimization just as your other networked applications do. All this improved efficiency helps you reduce costs.

Consolidate Your Operations

Whenever you can combine operations, eliminate points of failure, and consolidate administrative overhead, you benefit. VoIP uses the same standard protocols universally employed by other networked applications, reducing complexity and increasing flexibility. Because a VoIP phone system uses the same platform as your other applications, in the same way, it can take advantage of the broad capabilities and enhanced efficiencies of your data network.
