We’ve come a long way from the very first phone lines constructed during the 19th century. The change was inevitable.
After all, technology continually evolves to encompass more functions and provide better convenience.
We crave an easy life. That’s what pushes these advancements, and SIPs are an excellent example of that. In light of that, this article tries to define SIP in a clear and concise way. We’ll also discuss some of the benefits clients gain from this kind of service.
Ready to get stuck in? Let’s get to it.
Beginnings of Modern Communication
For a long time, PSTN (public switched telephone network ) lines were our primary mode of communication.
However, there were undeniable drawbacks to it – both sides had to be connected; otherwise, the connection will not happen. This required physical connectivity via cables and similar tools.
It was inconvenient at worst and clunky at best. These issues gave start to the mobile network because it eliminated the need for physical connectivity, but retained the way to make phone calls from one device to another.
Mobile services were appreciated, but they had their own problems, not the least of which was the cost.
In the modern world, be it well established or upcoming business, saving money on phone bills can be game-changing. Ultimately, the VoIP service appeared.
We can’t define SIP without understanding that VoIP is an acronym for Voice Over Internet Protocol. As you may have guessed, it uses the internet for connectivity purposes. This basically eliminates local phone companies from the equation.
The ability to connect directly to the PSTN might sound familiar. PRI (Primary Rate Interface) was created to set up such connectivity.
However, this was an expensive endeavor, requiring hardware and cables, and it needed to be maintained. PRI did not offer a cheaper solution, and so SIP came into the picture.
How to Define SIP?
Often likened to VoIP, SIP isn’t the exact same thing. VoIP can be considered as a broad term for all voice transmissions made via the internet, while SIP is only one of the branches.
SIP stands for Session Initiation Protocol, and it has many uses, such as establishing calls, connecting to email services, internet browsing, and many more. But the most significant utility SIP provides is called SIP trunking.
SIP Trunking is a hugely popular service that centers around securing smooth calling over the internet. It does so by assigning several SIP Channels. Also known as SIP Lines, these channels enable the user to make a phone call to private branch exchanges (PBX) all over the world. One line can facilitate a single connection; therefore, trunking (as a direct allocator of channels) is used to optimize the needs of the client further.
SIP vs. PRI
If we compare PRI with SIP, there is a significant gap in their capabilities. PRI has a set number of 23 channels available.
To some businesses, it can be too low a count, meaning they had to invest even more to duplicate PRI to get an additional 23 channels.
SIP does not have this problem. Instead, you can quickly increase or downsize in a way that fits your goals.
Depending on what SIP Trunking service you use, there are different counts of SIP Channels that might be available, and the number can be adjusted as needed.
Keep in mind, one person per call uses one channel. If you’re unsure of the number you need to cover your bases, specialists can help calculate an optimal plan.
We cannot talk about SIPs and not mention one of its biggest perks – cost efficiency. As this service doesn’t require additional hardware and utilizes the internet, there is greater flexibility in pricing.
You pay for your channels, as well as cover your regular internet bill. SIP Channel allows you to work with voice, video, and data processing using one line.
This ensures greater dependability for your business, as information is provided via a single-mode.
Additionally, because the internet is used to connect to the call, SIP Channels can secure a better quality call, with clear sound and little to no interruption.
It can be of great help when talking not only to clients but also when planning business-related strategies or relaying information.
If you’re worried about hinging such a significant part of your business on one service, you can use several providers.
In the case of one of your networks becoming temporarily unavailable, you’re not without any means of communication. An important thing to remember is that SIP requires your own PBX that is capable of connecting to the internet.
We Hope You Learned Something
To sum up, when it comes to making calls in the modern age, SIP is setting a standard with trunking and SIP Channels.
It eliminated the necessity for physical equipment and utilized digital connectivity. This method saves money for the user and is easier to maintain.
The channel count can be adjusted by increasing or decreasing the required number at any time. Therefore, you’re not stuck with a pre-determined count and can expand according to your workload.
Such intricacies might not allow us to define SIP in a sentence (or two). Still, SIP Channels use the internet to maintain smooth operations at a lower cost when compared to regular phone service providers.
