In the digital age of emails and Skype, is voice still relevant? The answer is, of course, yes. Voice calls are still the lifeblood of most companies around the world, especially if there is a sales or support aspect to their business. It remains vital for every business to protect its voice infrastructure, allowing employees to communicate both internally and externally, no matter what.As companies look to reduce costs by moving to a SIP trunking service, they must also consider both the resiliency of their network and planning for what happens in the event of a disaster. Let’s take resiliency first. It is obviously important to ensure that inbound and outbound calls are always available and of the requisite quality to ensure a good user and customer experience. This means that resiliency must be embedded at each layer of the infrastructure. For example, POP resiliency and trunk resiliency ensure that if the original calling destination fails, calls can be re-routed which means that the transition is seamless so users and customers remain unaware and can conduct business as usual.Secondly planning. Recovering from disasters and outages can be a difficult task and one that many organisations don’t want to contemplate, but it is this planning for the unexpected that can save your business if the worst happens. Disaster recovery (DR) and business continuity (BC) planning are an important part of building your communications infrastructure; businesses need to have a back-up plan in place to protect against incidents that prevent inbound and outbound calls being business as usual. That might be a building going up in flames or a power outage but events such as transport strikes are also disruptive creating a need for people to work from different locations. Having the ability to re-route calls to alternative numbers means that organisations can carry on as usual, without any impact on the business and the customer and user experience. Being able to support flexibility in this re-routing is vital: diverting Freephone numbers to a new location, re-routing number ranges to a different area code or to mobile numbers are all important capabilities. The latest version of Colt’s VoIP Access [SIP Trunking] solution includes enhanced DR capabilities, including call diversion to an alternative IP address, giving customers peace of mind that in the event of a disaster, a reliable alternative is in place.Of course, it isn’t just as simple as switching from one end-point to another. Careful planning has to be carried out to ensure the right processes are followed – this is especially pertinent in the event of a disaster, where time is money or the difference between life and death. Here at Colt, we work closely with our customers to develop a set of plans that follow an incident, and then subsequent plans to return the service back to normal. We believe this is what makes us unique to other SIP trunking services on the market; after all every business is unique so requires a unique approach to disaster recovery and business continuity.As the first point of contact for many customers with an organisation, voice calls should be treated as a critical asset – making sure these assets are protected by a comprehensive insurance policy is not only sensible, it is imperative.
