A Beginners Guide to SIP Trunking

In the world of telecommunications, there is no escaping the many acronyms used to refer to the solutions available. It would be very easy to avoid all of these terms and opt for the simplest of business telephone systems. However, the services behind these acronyms are vital elements of a high quality business comms package that will enhance and elevate your business.

One such important comms solution is SIP trunking, a major but often misunderstood service. With this in mind, our tech experts have put together a useful guide that breaks down exactly what SIP trunking is and how it can benefit your business.

What is SIP Trunking?

Put simply, Session Initiation Protocol trunking, otherwise known as SIP trunking, is a type of Voice over Internet Protocol (VoIP) that refers to calls being delivered over the internet. Using a Private Branch Exchange (PBX) to send and receive calls, SIP trunking is a replacement solution for the traditional Integrated Services Digital Network (ISDN) lines, that transit data and voice digitally over physically wired connections. With the impending demise of ISDN, businesses who haven’t already moved over to a more contemporary solution such as SIP, should strongly consider doing so imminently.

 Is SIP trunking cost effective?

In comparison to traditional ISDN lines, SIP trunking is less expensive to both maintain and manage daily, with businesses seeing a significant saving of up to 50% by dividing bandwidth between voice calls and data, through a single internet connection. Free UK landline calls are also offered, with much cheaper mobile and international calls also.

 Is SIP trunking reliable?

Power failures, line faults, natural disasters – these are all events that can occur at any time and result in your business experiencing some unforeseen downtime. To reduce the possibility of any financial loss, disruption to services and dissatisfied customers, SIP trunking provides incredibly effective disaster recovery that handles emergencies with ease. In the event of a ‘disaster’, calls will be automatically routed to an active broadband connection, thus removing the need to have a parallel set of lines installed, for when these unforeseen situations occur.

 Can SIP trunking handle business growth?

One of the most important business benefits of SIP is its ability to be completely scalable. For expanding businesses, SIP can grow with you to reflect your development by giving you the opportunity to add new lines and locations without any noticeable disruption. Should you need to move to a larger location, relocating with SIP is a smooth and uncomplicated process, even giving you the option to keep the same phone numbers. SIP trunking can easily grow as your business grows, and also cater to busier periods by allowing you to increase your resources as and when you need to.

Is SIP trunking suitable for a remote and flexible workforce?

For remote and flexible workers, a decrease in productivity isn’t an issue, as SIP allows your business to connect your employees’ mobile devices via flexible, securely installed VoIP apps that can integrate with a SIP based business phone system. This results in a fully accessible and connected team, regardless of the location of individual members of staff. Furthermore, if your internet connection fails, the mobile attributes of SIP will ensure you’re able to maintain communication throughout your business.
