What Is SIP Trunk and How Does It Work

What Is SIP Trunk?

The conversation about effective and modern business communication is impossible without mentioning the SIP trunk. SIP is an abbreviation of session initiation protocol and it works as a modern communication framework that helps you start a conversation and terminate it. A SIP trunk is taking the business communication and telecom world by storm. According to recent research by TMR, the global SIP trunk service market is going to grow 13 folds by the year 2030. Furthermore, the SIP market value is going to reach a whopping 35.5 billion dollars by the year 2030. These stats explain that SIP is not just the present, it is also the future. Companies that are keeping an open mind will be saving not only now but also in the future when the SIP industry will go through transformation by introducing new and advanced features. Although, there are so many SIP benefits, however, the future of SIP is much brighter.

Business models are now more advanced than ever, and their demands are changing. For daily communication, employees are no longer relying on audio calls. They are conducting daily video calls, conference calls, group video calls and offering the integration of these communicating software with the company management tools. All these things somehow are linked with SIP in one way or the other.

Framework Of SIP

SIP is the framework that offers good and seamless communication via the internet. To understand the fundamental aspect of SIP trunking, it is important to understand the jargons and acronyms that are used in the telecommunication and SIP industry. As we have already discussed that Sip stands for session initiation protocol and SIP trunking is the process of relaying voice and other communication services via the internet. When a user talks via SIP, the sound waves are not relaying in the form of Sound waves. Instead, these waves are converted into digital signals in the form of codes. Usually, for the initiation, rejection, and processing of the communication, a three-digit number is sent across. This number determines if the communication needs to continue to terminate at any time. SIP works with the use of IP-based PBX. Within the SIP-based communication private branch exchange replaces the traditional telephone lines.

What are SIP Trunks?

SIP trunks are virtual phone lines that help the user to receive and conduct calls via the internet. For companies handling their work remotely, SIP offers an internet calling facility for free. You can be at any place, any country, or any destination and you will still have easy access to your remote team. Companies are now allowing their employees to work remotely with SIP.  SIP trunks use a packet switch network and through that, they conduct voice calls. When a person speaks, these sound waves are divided into simple digital packets and then this is transmitted across the internet towards the receiver or the second party.

Using Existing Phone With PSTN

Traditionally if we look at the communication that is conducted through public phones, we will see that public switched telephone networks are used for carrying out phone calls. With the help of PSTN communication is conducted via copper lines that carry the voice signals. The PSTN circuit-switched network requires a connection between the two points which means all the lines must be connected to the local phone station where the calls will be relayed to the second person.

Benefits Of Using SIP

With SIP there is no need for a physical line, instead, the communication is carried out through SIP channels. Each SIP trunk has a SIP channel, and this channel is used for incoming and outgoing calls. The main reason SIP trunk is becoming a business favorite is because of its ability to hold and relay unlimited calls. Your business can conduct multiple calls at the same time. Your business number will never go engaged and no matter how many people want to simultaneously conduct calls you do not need anything extra. Since SIP holds multiple channels at the same time, each channel is used for a different call.

How VoIP Is Different From SIP?

Now that technologies are changing and getting better, more companies are switching to newer and better ways of communication. Most businesses must choose between SIP and VoIP but since both include the internet and ensure better communication, it is only fair for people to get confused. For small businesses trying to figure out a better and more feasible communication option that suits their requirement, we have listed down a simple comparison to help them differentiate between both. Both SIP and VoIP are a bit technical, so you need to know about specific jargon and understanding of technology to know in detail about the communication that is carried out.

SIP and VoIP

Usually, SIP protocol and VoIP are used for any internet-based communication however they are not the same. VoIP is the voice-over-internet protocol, and it covers so many different aspects of modern communication that are carried out through the internet. VoIP includes different internet protocol-based technologies and SIP protocol is an example of VoIP. SIP is a framework used for VoIP that offers seamless communication via the internet. You might have seen various apps for sip and sip trunk uk calls as well.

For the communication of voice, there is no way to relay sound waves directly to the second party. Before relaying the audio, signals are converted into digital signals that are then transmitted through the internet. When these digital signals reach the receiver, they are then converted back into the uncompressed audio signals are this is picked by the person who is listening on the other side. This technology or compressing and decompressing the audio signals make VoIP technology possible.

Popular Codecs for SIP

Most people ask about the levels of compression and how things we say are converted into signals but are not destroyed. To understand this, it is very important to know that various codecs have various levels of compressions. For the SIP trunk, there are three-digit numbers. Some of the most popular codecs for SIP include G.711 and G729. Both these codecs offer a very high-quality voice and you do not have to use any high-quality internet. There is no doubt that good internet is important, but they do not require too much data and even if you have some issues with the internet or have weak signals, there will be no effect on the service or the voice quality.

How system Helps Businesses?

Now that we are talking about voice quality and how it is so much better than the traditional telephony method. It is also very important to discuss that high definition and crystal-clear voice quality are possible with the use of SIP. For business, communication companies emphasize voice quality because sometimes they have online meetings where a whole team is dependent on the progress of their work, on the voice they hear. With the help of VoIP, you can have a high-quality voice that is crystal clear and much better than a traditional phone. However, for better quality, it is very important to have a good grade of the network because it must carry voice and be used by the SIP service as well. Most companies suggest that only tier 1 carriers can connect directly to the internet backbone so the call quality for them is better and more reliable.

What is QoS?

Most people might have noticed that no matter how you are using your data if there is an incoming call, it gets the data preference. This is done via QoS or quality of service. This is a router setting used for prioritizing the voice calls over everything else that is happening. It is also imperative because a voice call needs and consumes constant data. If you are browsing a website, a few seconds of lagging or data loss will not impact the process. It will retrieve the same file from your cache, and you will still be able to retrieve it. On the contrary, if you are on a voice call and there is some data loss, you will instantly feel the impact. The voice distortion will be bad, and you might even lose the message in the process. With the help of QoS, audio quality can be maintained throughout the conversation. No matter how the rest of the data is being used, this will have no impact on the overall quality of the audio call.
