How does SIP trunking work?
Session Initiation Protocol (SIP). Does that mean anything to you? Let’s start at the beginning. SIP trunking is a telephony technology that enables businesses to make and manage calls over a single data connection. It is a method of sending voice and other unified communications services over the internet; essentially, SIP trunks are virtual phone lines that enable users to make and receive phone calls over the internet to anyone in the world.

What are the benefits of SIP trunking?
- Businesses in 2021 can save up to 50% on telephone line rentals and 25% or more on call costs. As a result SIP trunking delivers less costly, more reliable connectivity.
- SIP has minimal upfront investment costs and firms can appreciate cost savings from their very first bill, showing an immediate RIO.
- Benefit from free internal calls between connected sites, with the peace of mind that service and call quality will never be compromised.
- SIP trunking guarantees total flexibility with your phone numbers; no matter where you relocate, you will be able to keep your existing numbers. And should your business need to up-size or down-size, no problem! You can add lines, take them away and split calls at a moment’s notice.
- SIP trunks are set up to reroute calls, quickly and easily. Rest assured that should a disaster occur, your phone system will stay operational.
- SIP trunks can be integrated to work with Microsoft Skype for Business, allowing you to directly connect to this platform to make external calls.
What can I expect from call quality with a sip trunking service?
SIP trunks allow for clear and reliable call quality. From the moment you are connected to your SIP trunking service, you will have your call quality proactively monitored and managed, including reliability and resilience, guaranteeing an unrivalled experience on every call.

What is the difference between SIP trunking and VoIP?
So, what is the difference between sip trunking and VoIP? The two cannot truly be compared for the following reason: VoIP does not require SIP in order to function and describes the method of delivering voice communications over the internet, whereas SIP is just one of the protocols that allows VoIP to function and is the most common. Using SIP with VoIP together increases both scalability and versatility, allowing users to expand into video, messaging and more.
Is SIP better than VoIP for my business?
No two businesses are the same, so careful consideration needs to be given to whether SIP trunking will enhance your business. However, sporting a reputation with few disadvantages, SIP trunking is ideal for those firms looking to glean the benefits of internet-based phones and make the move to the cloud. With no more confusing phone bills, unreliable, poor quality calls or high call costs switching to sip is beneficial for any business looking to future proof their phone system.

What is the difference between SIP and ISDN?
SIP trunking is a newer technology, allowing a business to carry both voice and data on the same channel. ISDN is a traditional technology, with calls being made over copper and fibre telephone lines using analogue signalling. BT announced in 2015 that their PSTN lines are scheduled to be switched off from 2025, so this aging technology will soon become obsolete. It’s all about the cloud from here on.
