sip callingWith the development of technology, we have been obviously moving away from miles of copper cables and long, daunting manual installation. But how can you choose the best of new solutions appearing on the market?

Below, we explain the intricacies of the Session Initiation Protocol – SIP for short. It can truly transform the communication quality within your organization. Read on to find out what SIP Calling is, how it works, who can use it, and why it should be you!

What Is SIP Calling (Session Initiation Protocol)?

As we have already mentioned, SIP stands for Session Initiation Protocol. It refers to a type of signaling protocol, which allows different systems to use an internet connection (Wi-Fi or another technology) to exchange information with the help of an SIP trunk or an SIP channel. The forms of exchanged information can vary, but most companies choose it for phone and video calls.

SIP calling uses both SIP and VoIP technologies, making it a great alternative for traditional phone lines and PRI lines.

From the security and ease of use to lower prices and the possibility to work with it on various devices, SIP calling might bring a great number of benefits to your organization.

How Does SIP Calling Work Exactly?

What makes SIP calling possible is an SIP trunk – a virtually established phone line using SIP technology. Its great advantage is that it enables a direct connection, eliminating the need for PRI lines (Primary Rate Interface) connecting PBX (Private Branch Exchange) to PSTN (Public Switched Telephone Network), This means you can connect directly to your old hardwired number and implement an upgrade to your existing system without having to start from scratch.

SIP calling work

Since the link is created with the internet, SIP calling takes advantage of its connection speed, no matter the used technology (Wi-Fi or not), which probably already is top-notch if you work online.

As such, the only thing you physically need will be handsets.

The SIP knows how to check if your recipient is available and capable of taking such calls. Then, it also disconnects automatically when the conversation ends, which reduces the overall costs.

Why Should You Use It? – The Benefits of SIP Calling

It’s Easy

First of all, you don’t need to establish the whole network from the very beginning. You can easily connect your old numbers and simply continue to make and receive calls with the use of SIP technology.

What’s more, you will be able to manage everything from your account, thanks to an intuitive interface of the online control panel. You will be the one responsible for new and old phone numbers, redirecting, extensions, and so on, so everything will be under your control.

With an SIP trunk, all the important features will be consolidated in one device, making it much easier and quicker to train your staff.

It’s Scalable

Since the whole network is cloud-based, once you’re using SIP calling, you can easily adjust it to the needs of your business. Whether your organization is growing or you look for ways to reduce costs, it will only take one call to your SIP provider to introduce changes, as most of them offer flexible billing, or even better – some companies allow you to manage your whole SIP phone plan yourself.

There’s no need for additional cables and complicated and time-consuming installation each time you hire a new person. Not to mention that SIP trunking will save you lots of office space.

Grow as you go without the need to try and predict the future so that you can have a phone waiting for every potential employee.

It’s Cheaper

Using SIP technology for audio and video conferencing will significantly lower your business phone bill. Most importantly, it doesn’t charge you for every minute you’re on the phone the same way as a traditional landline or mobile; SIP offers what you can truly call unlimited calls.

Moreover, there’s no hardware involved, which also means that you won’t have to spend time and money on purchases, installation, and maintenance.

Since it’s all cloud-based and works over the internet, it makes an especially significant difference when it comes to international calls (which are then treated as local calls), as they tend to be extremely expensive with a traditional phone.

What’s more, SIP-to-SIP calls are usually free. You can eliminate worries about the high cost of phone setup and focus more on your work.

It’s More Reliable

As SIP calling technology works over the internet, all you need to care about is the quality of your internet connection. Considering that digital processes and availability are key to success in the modern world, you have probably got it covered. As such, you don’t need to worry about the quality of audio and video conferencing.

It will be even better than over a regular phone, as SIP calling technology can extend the frequency range and increase the sample rate, meaning improving the audio and achieving even the HD quality. Consequently, you won’t have any problems understanding the person speaking, which is crucial in the case of conversing with customers or business partners.

Besides, when you use a traditional phone, you’re susceptible to the outside problems – bad weather conditions and power outages in the neighborhood or the network failure of your provider. With your own SIP network, you only need to make sure your internet is working.

And in case of a power outage or another failure within your company, you can redirect the phone calls to other locations or mobiles.

It’s Flexible

SIP calls can be received on a variety of mobile and laptop devices, including analog desk phones and VoIP softphones, allowing employees to access the phone system from wherever they are.

It can better enhance productivity and efficiency, and allow employees and customers to connect with each other through devices all over the world.

It’s Built-in Redundanct

Establishing SIP trunking doesn’t mean it will only replace your current phone line – it can also provide other useful features to your business, many of which overlap with the ones offered by VoIP systems (Voice over Internet Protocol).

These functions include the possibility to determine someone’s availability and location, media capabilities, managing phone, and video calls, enabling emergency calls and instant messaging, conferences, and so on.

Therefore, choosing an SIP calling system will help you eliminate at least some redundant software and hardware.

SIP or VoIP?

This really is not the right question. It’s not like you need to choose either one; the two technologies are more complementary than rivaling.

VoIP is the technology allowing audio and video transmission with the use of the internet. As such, SIP calling is more of a result of VoIP’s existence. VoIP needs a system (e.g., a computer) to work while an SIP phone exists outside it.

In short, VoIP is a much wider term, but it’s best to have both working together for the success of your business.

SIP calling is definitely something that can benefit your business tremendously. You don’t want to be left behind with an outdated phone system. VoIP and SIP phone and video technologies are here to stay – there’s no doubt about it. So, the sooner you start the transition, the better.
