As VoIP technology continues to grow in popularity, a wide variety of terms and acronyms that were once limited to the vocabulary of dealers and resellers are beginning to find their way into the mainstream.
An example of such a VoIP-related term used in proposals and conversations is SIP trunking. It is a system of connecting the public switched telephone network and a data network.
In another word, SIP Trunking allows companies to use a telephone Private Branch Exchange for sending and receiving calls over the Internet instead of the standard Public Switched Telephone Network.
Investing in unified communication services is essential for a modern business. The significant cost savings of SIP Trunking can help you get a return on investment. So, let’s learn more about SIP trunking, how it works.
What is SIP Trunking?
SIP (Sessions Initiation Protocol) is a protocol for establishing voice connections over the Internet. It is a standard-based protocol used to conduct audio and video communication within and across networks.
Trunking is a way to connect multiple points to the proper receiver by unifying multiple channels in one network. It enables network nodes to connect to corresponding network nodes on the other end of simultaneous calls that are routed through a single node.
A SIP trunk is a logical connection from one point to another over the public Internet, rather than physical cables delivered from a service provider to a business.
It uses SIP to connect the PSTN to a customer location via the Internet. Its main purpose is to connect customer locations and Internet telephony service providers (ITSPs).
How Does It Work?
You can connect your on-premises phone system to the Internet Telephony Service Provider (ITSP) with SIP Trunks. It establishes a telephony connection to the Internet using Session Initiation Protocol (SIP).
It may be a simple voice call between two clients or a conference call that involves a number of participants on different phone systems. Depending on the organization’s needs, one or more communication channels could be included in the PBX system.
SIP trunks can carry multiple SIP channels, each acting as an inbound or outbound channel. It connects IP channels to PSTN or VoIP systems which allows multiple simultaneous calls.
This will allow your company to contact customers and other companies as and when necessary.
It lets you make local, long-distance, and international calls using the Internet by connecting one, two, or twenty channels to your PBX.
A provider can connect to your phone system directly so that you can make outbound calls directly from it without having to limit how many calls you can make at the same time.
What are the Benefits of SIP Trunking?
SIP trunking offers extra flexibility when adding additional phone lines to your business. As your business grows, you won’t have to allocate one number for each line, and you’ll get more affordable pricing options, making SIP trunking both more scalable and more affordable than traditional telephone systems.
The following list highlights some of the various advantages that you will gain from using SIP.
Compared to traditional phone lines, SIP trunks are relatively inexpensive. Furthermore, you will benefit from a more stable connection to get a higher quality service for a lower rate.
Using this connection will allow you to transfer important business files and information. Instead of being forwarded through traditional phone lines, SIP calls route over the Internet, making these calls less expensive.
Businesses that operate globally and rely on international communication will find this even more useful. Businesses can use SIP trunking to forward calls internationally through international phone numbers, lowering long-distance calling costs.
2. Cost reduction
Cost-effectiveness is one of the biggest advantages of SIP Trunking. Businesses typically use a small portion of their bandwidth for data transmission. Because of this, most of their available bandwidth goes unused.
Using SIP telecommunications can often eliminate the need for data and voice circuits. Similarly, you can synchronize all the local line numbers and trunks on your service provider’s network. By doing so, you can eliminate the need to buy from multiple vendors and thus reduce hardware and local network trunk costs.
Furthermore, your company will be charged differently for long-distance, local, and international calls using traditional phone lines. By switching to SIP providers, businesses typically enjoy predictable monthly costs, and they can instantly get access to simple and understandable pricing.
It is challenging to grow traditional phone lines. With SIP, it’s simplified as a Physical landline is not necessary for SIP Trunking. In other words, you can continue to add a line over the Internet whenever necessary.
Scalability is one of the most appealing aspects of SIP trunking. Your system can be organized, added, and managed based on the specific needs of your business. With SIP trunks, you can operate multiple virtual lines at once, as they host unlimited channels.
SIP Trunking makes your company’s capacity very flexible, so you will only ever pay for the call volume and numbers you require.
4. Enhanced security
Since SIP trunks connect calls via the Internet, they are often safer than ISDN when paired with robust internet security measures. SIP providers normally provide fraud alerts as well as firewalls that integrate with the communications software.
Communication handled through SIP is one of the safest and most secure options if all security measures are in place and regularly updated software.
5. Unified Communication
You and your employees can take advantage of elastic trunking and cloud communications from a single platform for all communication and business services. All employees are able to record and share voice messages, videos, and texts, as well as other files.
Keeping your teams well-connected and accessible information when and where they need it will help keep them well-informed.
A unified communications system improves productivity, increases consistency, more flexibility, and offers greater reliability. It allows you to manage all of your cloud-based communications in one place – it’s definitely a small business’ dream to achieve that level of organization and control.
To maintain your connection, you can’t always rely on weather conditions, disasters, telephone pole problems, or random phone company problems. There is no alternative for telephone networks when telephone poles are damaged. Playing the waiting game is your only option.
Would you like to leave your business at risk of being unable to communicate wherever or whenever needed? But, if you consider SIP trunking and other internet-based phone services, you can control your connection as long as an internet connection is working properly.
Not only that, but you can also make multiple plans in case of a network outage. It’s also not necessary to wait for contractors because your own IT department manages it.
