Being a business owner, you may already know the importance of communication. And streamlining communication infrastructure is even more crucial in business workspace. 

But you might be wondering how you can do it. The simple answer to your question is to implement SIP trunking in your business communication. The term SIP trunking might not be familiar to you. 

No need to worry, we are here to guide you. This blog will cover everything about SIP trunking, including what SIP trunking is, its benefits, and how you can implement it in your business. So, read till the end to learn everything about it.

What is SIP Trunking?

SIP stands for Session Initiated Protocol. It is a way for businesses and individuals to make and receive calls over the Internet. It enables voice over internet protocol phone calls such as video conferencing and voice calls. 

SIP Trunking uses a dedicated internet communications channel called a “trunk” and the Session Initiation Protocol (SIP) to connect, disconnect, and maintain calls.  You can use this telephony protocol to set up an audio or video conference over the phone. 

Importance of Streamlining Communication Infrastructure

Streamlined communication infrastructure means simplifying and improving the communication system in your organization. It does not mean you are applying different ways to interact with your customers, partners, and employees. It does mean you are building an effective relationship with each and every one of them. 

Streamlined communication infrastructure is essential to make data access easier for your employees. With it, you can eliminate unnecessary data and make a clear path of communication. Further, it helps to maximize productivity as employees can spend more time on important tasks. 

What is VoIP?

Voice Over Internet Protocol is a modern telephony that enables voice communication transmission over the Internet. VoIP does not use telephone lines, hardware, and physical infrastructures, unlike traditional business phone systems. You just need a device and a good internet connection to make and receive calls with VoIP.

VoIP technology converts a user’s voice signal to digital data via the internet. Signals from regular phone numbers are converted back to telephone signals before they reach other users.

How SIP Trunking Works?

SIP trunking works by dividing voice calls into digital packets and sending them across a data network. There are various components in SIP trunking, and those components work together to enable SIP trunking operation. The components of SIP trunking are discussed below.

SIP Channels

SIP channels are phone line that carries phone calls. It allows you to make incoming and outgoing calls simultaneously.

SIP Trunk

Multiple SIP lines are grouped together to make an SIP trunk. It acts as a bridge to make connections between the company’s phone and Internet Telephony Service Provider (ITSP).

SIP Protocol

A set of communication rules for making and ending internet data connections is known as the SIP Protocol. It allows users to communicate with other parties via voice, video, or messaging services

SIP Provider

SIP providers are companies or businesses that offer SIP services. SIP providers group one or several SIP connections and run them through an on-premise private branch exchange (PBX).

Benefits of SIP Trunking

SIP connects voice, video, and text to connect individuals and businesses locally and globally. It helps businesses to become technologically competitive by simplifying communication systems. Here are some benefits of SIP trunking.

  1. Scalability

Every business grows, and sometimes it will grow at a rapid pace. SIP trunks are very easy to expand. Whether you need additional lines or toll-free numbers, you just need to contact your provider. To add new features or components, getting new hardware is not required.

Businesses that grow at an unpredictable and rapid pace can greatly benefit from this convenience of SIP trunk. You can easily scale up or down your phone system as your needs change. It makes it easy to instantly provide new employees with numbers or reduce phone system costs when you no longer need existing lines.

  1. Cost Savings

In a traditional phone system, you may need to pay for extra lines you are not using. It also charges for long-distance and international calls. With SIP trunking, you just need to pay on a per-user basis.

SIP trunks require only a reliable IP network to operate. Both set-up costs and process are simple and flexible, which allows to save significant amount of money. The best part is you get the option to choose between metered and unmetered SIP trunk plans.

  1. Business Continuity

SIP trunking lets your business run continuously, even during power outages and natural disasters. It prevents your business from unexpected events as you can set up backup routes for your calls.

SIP trunking provides remote working opportunities. Your employees do not need to be physically present at the office to receive calls. They can connect with customers and colleagues from their homes or any place. This ensures your business operation doesn’t hamper and keeps running.

  1. Enhanced Features

SIP trunking provides enhanced features to streamline your business communication. Voicemail to email allows you to send voicemail to email automatically. This makes it easy to manage and access your messages.

The call data records feature lets users get insights into their communication and review call history. Further, the disaster recovery feature helps to run businesses even at the time of power outages.

Implementing SIP Trunking

Implementing SIP trunking may vary depending on the requirements of the business. Some businesses may need just a few channels, while others may require multiple SIP trunks. So, depending on your requirements, implementing SIP trunking can be simple or very complex. Here are some common practices for implementing SIP trunks.

  1. Knowing What Your Business Needs

The initial step is to determine your business needs. Knowing your business needs is not just deciding the features and pricing, it goes beyond that. You must know how your business currently operates and how communication is carried throughout the department. 

By doing this, you will be able to spot areas where SIP trunks need to be implemented. Moreover, you need to determine if your existing network supports additional voice traffic. If it doesn’t support it, you may need to buy new equipment or upgrade it.

  1. Choosing a SIP Trunk Provider

Many providers provide SIP trunks in the market. You must choose a reputable provider with a good service. Make sure you are choosing the right provider that aligns with your business needs.

You must consider different factors while choosing an SIP trunk provider. This includes pricing, customer support, reliability, and the availability of features.
