How Many SIP Trunks Do I Need?

SIP stands for Session Initiation Protocol, which is the technology that allows voice and multimedia communication via an internet protocol. Trunking means the process of combining many communication channels or lines into a signal local connection or trunk.

SIP trunking is a telecommunication technology used to make phone calls and communicate via the Internet.

SIP trunks connect your phone system’s Private Branch Exchange (PBX) to the outside world through the Internet instead of traditional phone lines. When someone calls your business, it directly routes the call over the Internet.

With SIP trunking, you don’t require a separate line for each call; the SIP trunk can handle multiple lines on a single platform. This means it’s more flexible, scalable, and cost-saving than the traditional phone system.

Most businesses need only one SIP trunk. But if your business is large and needs to handle a large amount of calls, you might need more than one SIP trunk.

Certain factors, such as business size, communication patterns within the organization, and your potential growth projection need to be considered when calculating the SIP trunk. 
 

Business Size and Structure

Business size and structure are important factors to consider when determining how many SIP trunks your business needs. For example, if your organization has few employees and a low call volume, you need only one SIP trunk. But if your organization is big, with more employees and a higher volume of concurrent calls, you need more than one SIP trunk.  
 

Communication Patterns

Understanding how your business communicates is equally important. Do your employees frequently make a call? Is your business getting high call volumes for customer support? Businesses with heavy phone usage will need more SIP trunks than those with occasional calling.
 

Growth Projection

When calculating how many SIP trunks your business needs, consider your business growth, too. As your business expands, you may hire more employees, open new locations, or experience an increase in customer interactions. Even if your current call volume is manageable with a certain number of SIP trunks, projecting growth over the next few years helps you avoid future limitations.
