Benefits of SIP
As more and more UK businesses outgrow their current telecommunications solutions, the top three things that most are looking for are value, reliability and flexibility. SIP is able to outperform ISDN in all three of these areas.
With the popularity of SIP trunks showing no signs of slowing and the technology being the go-to solution for telecommunications the question is why would a business continue using ISDN? The answer is often that businesses haven’t investigated the options and so are not fully aware of the benefits of switching.
It is commonly understood that compared to ISDN, SIP is a cheaper option and now businesses are now realising that there are a wealth of other benefits that SIP provides beyond cost savings. For example it is more flexible in terms of what telephone numbers you can have and where you can have them and is also quicker to install as well as offering an extremely robust business continuity service that ensures your business never loses calls.
In the past SIP trunks had a bad reputation for reliability, but these issues have been addressed and the technology is considered extremely reliable. The bad reputation in early days often came from providers deploying SIP over inadequate low speed internet connections. Confidence in SIP is now much higher particularly among small and medium sized businesses that recognise the cost benefits and now have confidence in the speed of their connectivity, removing high latency, which was the main reason for SIP trunks dropping.
SIP is also the natural choice for unified communications systems such as Swyx, giving businesses the option to extend voice connectivity outside of the office and into the public network and also providing functionality such as user presence and Instant Messaging.
In terms of flexibility, SIP trunking enables a business to easily scale up or reduce the number of channels that are required, for example, in response to fluctuating seasonal demand. It also provides more options than ISDN when it comes to number plans.
Why use SIP?
Lower phone costs
Save on calls and line rental charges compared to your standard telephone bills. Calls placed over the internet are usually lower than traditional lines and could save you up to 50% compared to standard ISDN lines.
Use local numbers
Operate without geographic telephone number constraints. Telephone area codes can be used anywhere in the UK, as long as you have an internet connection
SIP lines take priority over bandwidth, ensuring your phone calls will never lose quality
With SIP lines there are no lengthy installs, adding extra lines is just few mouse clicks away and you can take your numbers should you move premises.
Benefit from additional features such as call reporting and call recording. These features enhance productivity and were traditionally only accessible to sizable call centres.
Are all SIP trunks the same?
Although SIP is a standardised protocol, services vary between different providers, based on a number of factors, with a key one being the infrastructure on which the service is delivered. Where reliability and security should be the top priorities. With its own data centre and point of presence, EBC Group are able to offer businesses a secure and reliable service. Businesses are also normally interested in call bundles or out of area numbering, which are both areas that EBC Group can offer excellent added value.
Will I save money with SIP?
The majority of multi-site businesses can make significant savings from SIP trunking, which can often be achieved through internal call cost savings alone (i.e. calls between branches). Even more significant are the savings that can be made when businesses centralise their telephony and aggregate their SIP channels. For example, a multi-site business can usually replace the ISDN lines at multiple locations with a centralised SIP trunk.
Converged Networks represent a further opportunity for cost savings. There is a growing number of businesses who have deployed high bandwidth connectivity into their sites which enables them to utilise these connections to handle their SIP traffic alongside their data traffic without the requirement of installing additional connectivity specifically for their SIP trunks.
Does SIP provide business continuity?
It is automated so a business will experience very little or no downtime. However as with any technology there is always the concern of what would happen if disaster struck, but with the right DR Plan a solution can be built to achieve whatever business continuity requirement business needs.
SIP provides the added continuity that a company’s numbers are virtual, so it can stay with them whichever location they are in or move to. This is particularly useful for businesses that want to make the most of remote working.
Is SIP secure?
Security around technology is a hot topic and SIP provides a number of features which help to keep it secure. Effective configuration of use of hardware such as SBC (Session Border Controller) which provides a firewall-type service and fraud management services both limit exposure to in the unlikely event of a service be breached. SIP is not any more
