What is SIP Trunking

Session initiation protocol (SIP) is a way for business phone interactions to be conducted over the internet instead of on a traditional phone connection. SIP trunking eradicates the need to be physically connected to a phone company. This new business communication service has helped organisations realise the savings that can be made on communications with efficient use. Frequently organisations do not make the much-needed move to SIP trunking because of a lack of understanding of the terminology surrounding the topic but, with explanation, it will become clear that it is imperative in the modern workplace.

How SIP works

SIP trunking is operated by SIP providers, which function similarly to conventional phone companies. The difference between classic phone service providers and SIP providers is that SIP provides phone service over the internet which is significantly less expense for your business.

SIP trunking works with a phone system called Voice over Internet Protocol (VoIP) which is based on SIP. This is the standard communications protocol for both video and voice communications across a data network in a Unified Communications solution. A SIP trunk is installed wirelessly over a business’ internet connection which makes redundant the need for traditional cables.

Benefits of SIP

There are a number of benefits to choosing SIP trunking over traditional phone connections. The most fundamental aid to business that SIP trunking provides is the cost efficiency. The savings can be up to 60%-80%.

Phone service reliability is another enormous consideration. The professionalism of a company can rely on something as seemingly small as having a clear, reliable phone line. SIP trunking with VoIP provides an increased reliability of services by producing a level of redundancy. If a system fails, SIP trunking providers can reroute services to a redundant data line. They can also forward the PBX to mobile phones to make sure your business doesn’t falter.

A frequently overlooked benefit is the lack physical hardware to maintain such as the wiring and circuit boxes that normally provide connection to a phone line. Similarly, it makes it easy to scale your operation. As a result of the virtual connection, SIP trunking can be added to or modified quickly and easily.

SIP Savings

The savings that are made from switching to SIP providers is considerable; sometimes as much as 80% less than a regular phone line. By reducing numerous phone lines down to one point of entry remarkably lowers the cost of incoming lines and any cost associated with the upkeep of those lines. Savings are also made with SIP trunking by being able to purchase only the number of lines your business needs as opposed to be confined to plans that offer excess physical lines. SIP trunking makes communication efficient.

A Direct Inward Dialling number (DID), or a phone number, is also inexpensive when purchased with a SIP trunk. When a DID is facilitated by a traditional phone company, a charge is applied as well as charges for the IT, maintenance and hardware that connect the physical lines. Receiving a DID without the need for this infrastructure is cost effective.
