Companies deploying PBX systems or IP PBX systems and want to implement VoIP technology need to establish a connection of the current infrastructure to the cloud-based system. This connection comes live by using SIP trunking. In general, SIP trunks have the same function as regular PSTN (Public Switched Telephone Network) lines, but unlike them, they are a virtual solution with no hard wires.
SIP trunking has its name from Session Initiation Protocol, which is established as the standard for initiating multimedia and voice sessions using IP. Calls placed over a data network follow the SIP protocol which enables communication over an Internet connection. Hard wired SIP phone trunks are used in all regular telephone systems and SIP trunks are the VoIP alternative to the analogue and digital ones.
SIP trunking consists of virtual lines, that carry multiple signals simultaneously and their delivery and operations are entirely through the Internet, following SIP. The phone number is linked to the SIP trunk, which can support several users.
This types of business telephone system offers a more transparent experience for users. Improved communication means for better customer service, and further lowering of costs for the company. Many businesses have integrated SIP trunking into their phone systems to take advantage of the flexibility and other advantages of the concept.

SIP trunks are virtual phone lines, so there are no wires or any kind of software to be purchased and installed. They are paid for with a subscription fee to a SIP provider, who takes care of establishing the connection of the SIP trunks.
SIP trunking offers many advantages to businesses, including cost saving and better communication options. To get a better overview of what SIP has to offer, they are divided into several categories:
The market for SIP trunk providers is full of offers and different service plans, but the decision on which one to choose should consider several important factors.
SIP trunks run on a private and public domain and are subject to cyber attacks, which can lead to loss or misuse of sensitive business information. Business owners should look for SIP providers who emphasize on protecting their customer’s information.
With more and more SIP suppliers on the market, prices go down, but it is still important to look for a service plan that offers the closest components to your business needs at a competitive price.
Maintenance of SIP trunks is held by the provider and it is crucial for them to offer rapid and adequate support to their customer’s problems and have available tech support at any time.
SIP trunking gives the opportunity for businesses to place international calls at the price of local ones, but providers have different rates. Evaluating them and finding the most suitable ones, corresponding to the business geographic coverage is a significant potential money saver.
Most SIP providers offer unlimited growth options as SIP trunks can be added to the system anytime and it supports an unlimited number of them. However, business owners need to make sure that the provider they are going for is able to handle their growth ambitions.
Although SIP trunking prices may vary, the usual range is between £15-35 per SIP trunk monthly, noting that one SIP trunk is able to handle roughly 2-3 users. There are also some initial setup costs for establishing the connection between the PBX and VoIP service, which can be around £30-150.
It is important to talk to your provider about the way they charge SIP trunks since some offer a price based on the number of call time and others have a generally higher fee per SIP trunk but also unlimited minutes.
It is generally perceived that SIP trunks aren’t as reliable as traditional PSTN lines since they are dependent on the Internet connection and electricity supply and this is why some companies tend to leave a few PSTN connected lines as a backup plan. However, most PBX systems support UPS (Uninterruptible Power Supply) and are able to function without electricity for a certain amount of time.
Internet connection is extremely important for SIP trunks to operate and companies need to make sure that their infrastructure is ready to handle such a system. There are some further issues with SIP trunking such as voice and data prioritization, but the latest solutions provide Quality of Service (QoS), which improves call quality and makes the system understand that voice data is the first priority.
