How Many Sip Trunks Does a Small Business Need?

Small business owners have to wear many hats. They often have to do their own research to be successful. They must find out what they need to take their business to the next level, figure out how to implement it, and determine how to do it on a budget, all while creating, marketing, selling, and working with customers. One topic that frequently comes up with businesses that handle any level of call volumes is SIP trunking.

SIP trunks, or Session Initiation Protocol trunks, have become a vital component of modern business communication. Particularly for small businesses, the question that is most often asked is “How many SIP trunks does a small business need?” The answer may surprise you, but you’ll need more information to understand and determine your unique needs.

In this comprehensive guide, we’ll define what SIP trunks are, explore how they benefit today’s businesses, and help you discover how many SIP trunks you may need for your business. In turn, you can get back to what’s most important: serving your customers.

Planning Ahead: How Many SIP Trunks Does Your Business Need?

A common misconception is that SIP trunks are exclusive to large enterprises. That couldn’t be further from the truth. The fact is that small businesses can implement SIP trunks to leverage the same cost benefits, scalability, and advanced features as larger enterprises, leveling the playing field in the business communication landscape. Let’s look a little deeper into what SIP trunking is and what it can do for you as a small business owner.

What Are SIP Trunks, and Why Are They Important for Small Businesses?

SIP trunks serve as the backbone of internet-based communication, allowing businesses to transmit voice, video, and other multimedia sessions. Unlike traditional phone lines, SIP trunks operate over the Internet, offering enhanced flexibility and cost-effectiveness.

People often use the terms SIP trunk and SIP channel interchangeably, but they are not the same thing. A SIP trunk is the connection between your phone system (PBX) and the public switched telephone network (PSTN). A SIP trunk is like a communications highway. A SIP channel, on the other hand, is the capability to support one incoming or outgoing call. Therefore, SIP channels are like the lanes for your highway. Each call takes up exactly one lane whether it is incoming or outgoing.

These defining characteristics are the first indicators that answer the question, how many SIP trunks does your business need? Because a SIP trunk can hold an unlimited number of channels, you only need one SIP trunk. The number of channels you need, however, will depend on the number of concurrent calls your business tends to make. Another factor in the number of SIP channels is the type of business your company is running. For example, a manufacturing factory would need a lot fewer SIP channels than a telemarketing company.

SIP trunks are critical for all businesses that handle calls but even more important for companies that are new or still growing. Small businesses often operate on tight budgets, making cost-effective communication solutions crucial. SIP trunks not only provide significant cost savings but also offer scalability and advanced features that empower small enterprises to compete in the digital landscape.

Determining How Many SIP Channels You Need

What makes SIP trunking so appealing to SMBs is the flexibility. Typically, the Primary Rate Interface (PRI), with its standard 23-channel circuit, exceeds the number of an SMB’s employees. With SIP trunks, you can get and pay for the exact number of channels that your business needs at any given time. SIP trunks also support remote workers better than PRIs because there’s no need for circuits and cabling, allowing employees to communicate from anywhere.

To determine the optimal number of SIP channels you need, here are three key factors to consider:

Factor #1: The Size of Your Business

The size of a business plays a pivotal role in determining the number of SIP channels required. Smaller businesses may start with a few channels and scale up as they grow, while larger enterprises may need a more extensive infrastructure to handle increased communication traffic.

If you own a small- to medium-sized business, a flexible phone system that allows you to grow your operations is ideal. At the same time, you’re also likely to be focused on your budget, and your company’s growth may be unpredictable. Your company could grow overnight, or you could stay the same size for years. That’s why it’s important to find a SIP trunk provider that allows you to order or cancel SIP channels on demand, without additional fees.

Factor #2: Communication Needs

Understanding the communication needs of your business is essential. Factors such as the volume of concurrent calls, the nature of communication (voice, video, or SMS), and the geographical spread of employees influence your SIP trunk requirements. The number of concurrent calls a business expects is a key factor in determining SIP trunk channels. Businesses must analyze their peak call times and plan ahead to handle simultaneous conversations.

SIP trunks rely on internet bandwidth to transmit calls. Businesses must assess their existing bandwidth and ensure it can accommodate the additional load introduced by SIP trunks. Adequate bandwidth prevents call quality issues and ensures a seamless communication experience.

Factor #3: Growth Projections

Forward-thinking businesses consider growth projections when planning for SIP trunks. Scalability is a key advantage of SIP trunking, allowing businesses to adapt their communication infrastructure as they expand. Where legacy telephone systems rely on landlines that tie an enterprise to a physical location, making it very difficult and expensive to scale, SIP trunks allow modern businesses to operate from virtually anywhere as the business grows and its needs change.

The Top 3 Benefits of SIP Trunks for Small Businesses

With a better idea of how many sip trunks your business needs, it’s time to explore the benefits of cloud-based communications. SIP trunks help bring your business communication into the virtual world. Today, SIP trunking enables companies of all sizes to operate from virtually anywhere, keeping your employees, suppliers, vendors, and customers connected.
