Guest View: The Promise of Cloud UC – Debunking the common myths

Pierre-Jean Chalon, Vice President and General Manager, Asia Pacific, Sonus Networks | March 31, 2014
Let's dispel some common myths related to security, reliability, cost and transition of Cloud UC.


Much like your mobile phone contract, it is crucial to examine the terms and conditions of any agreement. With Cloud UC, businesses have much more flexibility to control what they want to pay for and what they don't. For example, if a business does not want to pay a monthly fee to rent a desk phone when all they need is a mobile client for their smartphone, they have the ability to make that choice.  If they need IVR capabilities in some locations and not others, they have the flexibility do so too. Ultimately, the business's requirements need to line up against the contract terms. Again, much like a mobile phone contract, the biggest 'gotcha' is typically early exit fees.


When shopping for a Cloud UC provider, it is important to ask what happens in instances of natural disasters. Often, Cloud UC users can continue working since all they have to do is move to anywhere that has Internet access and continue being productive.  During the evaluation process, every company should ask simple questions specific to redundancy, data centre location and the steps taken to ensure service remains consistent across all scenarios.

Expanding Cloud UC seamlessly  

While the financial impact of Cloud UC can be compelling, the real prize lies in the expanded capabilities it brings to businesses of all sizes.  What is also important, of course, is that these UC tools are extended seamlessly to meet the needs of companies. 

This is where Session Border Controllers (SBCs) come in. SBCs provide secure access to SIP trunking, which enable enterprises to simplify their network design, reduce costs and effectively deploy new applications including UC and video. Because UC consists of primarily SIP-driven sessions, the SBC has the dual function of both SIP enabler (as the SIP gateway for the network) and SIP mediator for the various applications and devices that make up the UC environment.

An SBC provides the cornerstone for SIP communications in a UC-centric network, by providing a common gateway/controller for internal and external SIP-based applications and devices. The SBC also takes care of the issue of security as attacks such as flooding or denial of service (DoS), are discarded by the SBC without impacting performance or scale. In addition, SBCs help break down silos and integrate a company's video endpoints by interworking different protocols and devices to enable one seamless end-to-end video experience.

Environments with a high concentration of knowledge workers can benefit from advanced UC capabilities for collaboration and real-time collaboration. These features become even more important as you try to knit together an organisation between disparate locations. When coupled with significant cost savings ranging from 40-60 percent, these added capabilities are typically available in an easy-to-deploy, simple-to-use type package, making the transition to Cloud UC especially appealing.
