SIP trunking, or Session Initiation Protocol, is the technology that is intended to replace the older legacy technologies of ISDN and PSTN. With BT’s impending switch off of its ISDN lines, there has never been a better time to look at updating your business phone service.
SIP trunking is a form of telephony that is becoming increasingly popular in the business world because it is the technology that delivers VoIP telephony for businesses all over the UK. There are many benefits of SIP trunking, including increased reliability, cost-saving opportunities and flexibility.
SIP Trunks are essentially virtual phone lines that create a connection from your business to the phone network via the internet, instead of traditional phone lines. This connection means SIP trunking is far more flexible than traditional ISDN networks and is also much cheaper to run with reduced infrastructure and maintenance costs.
SIP trunking removes the need for old PBX switchboards and Public Switched Telephone Network (PSTN) lines on premises. Instead, all you need is a broadband internet connection.
SIP trunking is 30–50% cheaper than traditional telephone lines and is the fastest growing telephony service in the world. SIP trunking is a reliable, cost-effective voice service that is cheaper and more flexible than traditional digital or analogue phone lines.
SIP trunks can save your business money on both your phone line rental costs and call costs. The development and reduced price of SIP have also made VoIP a more viable option for many businesses.
Unified communications are the ability to integrate all of your business’ communications into one manageable strategy. SIP trunking is a huge enabler of unified communications and provides the user with the ability to make use of the same phone number regardless of which device they are using.
In the event of a disaster or line fault, calls can be automatically routed anywhere else that has a broadband internet connection. This removes the need to maintain a parallel set of phone lines as a back-up and aids in rapid disaster recovery.
The main advantage of our SIP trunking service is its flexibility. It is completely scalable to your business requirements. Instead of having to buy and install a certain number of fixed lines, SIP trunks can be scaled up or down in line with demand and without the need for additional physical line installation. This is very important to those businesses who are expecting growth or seasonally-related busy periods. SIP can be scaled up and down with ease and can support an unlimited number of channels and therefore calls.
With traditional ISDN phone line technology being phased out by 2025, SIP trunks are here to help future proof your business whilst saving you a significant amount of money on your existing line rental and call costs.
Our SIP trunking service is for those who are looking to reduce the cost of their phone system whilst also keeping a high call quality and quality of service.
SIP is dependent on connectivity, however, so it is important for you to be aware of your business requirements, such as the volume of inbound and outbound voice calls and how large your bandwidth requirement is. A dedicated data connection is the best way to ensure reliability for your voice traffic.
