SIP Trunk Pricing Can Be Confusing: Here Are the Basics

As businesses seek to optimize their communication infrastructure, SIP trunking stands out as an efficient, cost-effective solution. The rapidly growing SIP trunking services market, projected to reach $22.99 billion by 2028 with a compound annual growth rate (CAGR) of 10.7%, underscores its increasing importance. However, navigating the pricing structures of various providers can be challenging for those new to this technology. 

As the market becomes more competitive, a SIP trunk pricing comparison becomes essential for businesses looking to optimize their communication infrastructure while keeping costs in check. This can be challenging since industry experts often use terms that are not familiar to people who don’t think about SIP for a living. This guide aims to clarify the key components of SIP trunk pricing and help you navigate the intricacies of comparing offers from various SIP trunking providers.

Before SIP Trunk Pricing Comparisons: Understanding the Basics

Much of the confusion about pricing for SIP begins with two terms: SIP trunks and SIP channels. People often use them interchangeably, but they are not the same. A SIP trunk is simply the connection between your phone system and the public switched telephone network. Think of it as a tunnel for a highway. A SIP channel is the capability to support one incoming or outgoing call. You can think of SIP channels as the lanes for your highway. Each call takes up exactly one lane.

When conducting a SIP trunk pricing comparison, it’s crucial to understand that because a SIP trunk can hold an unlimited number of channels, you only need one SIP trunk. The number of channels you need will depend on how many concurrent calls your business tends to make. SIP channels are sometimes called sessions, lines or concurrent calls. They are similar in practice to a traditional telephone line.

In terms of pricing, most vendors don’t charge for the trunk. The monthly fee is based on the number of channels you require. This is a key factor to consider in your SIP trunk pricing comparison, as it directly impacts your monthly costs.

Estimating Your Channel Needs

Most businesses don’t need a channel for every employee because it is unusual for all employees to be on the phone at the same time. Depending on the nature of your business, you may need as few as one channel for every 3 or 4 employees. Of course, if you have a call center or other heavy telephone usage needs, you may require more channels. If employees or callers complain about busy signals, you likely need to increase the number of SIP channels.

When comparing SIP trunk pricing, it’s essential to accurately estimate your channel needs to avoid overpaying for unused capacity or experiencing call quality issues due to insufficient channels.

Unlimited Calling Plans: What They Really Mean

Another term that can introduce confusion into SIP pricing is the use of the term “Unlimited.” As we said earlier, SIP trunks are sometimes called unlimited because they can support any number of SIP channels. Without the channels, however, the SIP trunk isn’t useful.

“Unlimited” may also be used to describe the calling plans offered by providers. This usually means that the provider does not charge based on usage for calls to the lower US 48 states and parts of Canada. As long as you are calling those areas, you will pay only your monthly fee for each SIP channel and no additional long-distance charges—regardless of how many calls you make or how long you talk. Calls to other parts of the world are charged based on the per-minute rate for that location.

When conducting a SIP trunk pricing comparison, pay close attention to what “unlimited” really means for each provider. Some may have fair usage policies or exclude certain areas from their unlimited plans.

Additional Costs to Consider in Your SIP Trunk Pricing Comparison

While the core pricing of SIP trunking services is crucial, a comprehensive comparison must take into account several additional costs that can significantly impact your overall expenditure. These often-overlooked elements can make a substantial difference in the total cost of ownership and may vary between providers. Understanding these supplementary expenses is essential for making an informed decision and avoiding unexpected charges down the line. Let’s explore some of the key additional costs you should consider when comparing SIP trunk pricing:

1. DID Fees

If you need direct inward dialing (DID) so that each employee or certain employees can be reached with a unique 10-digit number rather than a main number plus an extension, there will usually be a minimal additional monthly fee for each DID.

2. Nomadic e911

Nomadic e911 is an important service that enables users to set any address in the United States as the address to be transmitted to the nearest Public Safety Answering Point (PSAP) when a call is placed to 911. Landline numbers do this automatically, but digital lines need to be set up for this service. This is essential so that emergency responders can quickly get to where they’re needed. There is usually a small monthly fee associated with this service for each number.

3. Set Up Costs

You can expect some initial set-up fees for SIP trunking. This generally includes s fee for each SIP channel and each DID. If you will be moving your current phone numbers to your SIP trunk, there will also be a porting fee for each number that you wish to retain.

4. Taxes and Regulatory Fees

Of course, SIP services are not exempt from government taxes and fees. Specifically, the Federal Universal Service Fund (USF) is a necessary fee that helps ensure that first-class, affordable telecommunications services are available to customers in all parts of the country, especially rural areas where providing service would not otherwise be profitable for telecom carriers. The Fund also provides discounted communications services for certain healthcare facilities, schools and libraries.

All telecommunications providers are required to pay into the Federal USF, and their contributions are routinely passed along to customers. The fee is a percentage based on a contribution factor announced by the FCC and is subject to modification by the FCC.

When comparing SIP trunk pricing, be sure to ask about these additional fees and how they factor into the overall cost.

Advanced Features and Their Impact on Pricing

As you conduct your SIP trunk pricing comparison, consider the advanced features offered by different providers and how they align with your business needs. Some key features to look for include:

1. Scalability and Flexibility: The ability to easily add or remove channels as your business needs change.
2. Compatibility: Ensure the provider supports your existing PBX system or offers solutions for legacy systems.
3. Security Measures: Look for providers offering robust security features, including fraud detection and international calling thresholds.
4. Disaster Recovery Options: Consider providers that offer automatic failover and the ability to redirect calls in case of system failures.
5. International Calling Capabilities: If your business operates globally, compare international rates and policies on international call fraud protection.

These features can significantly impact the value you receive from your SIP trunking service and should be factored into your SIP trunk pricing comparison.

The Hidden Costs of Cheap SIP Trunking

While it’s tempting to choose the provider with the lowest prices in your SIP trunk pricing comparison, it’s crucial to consider the potential hidden costs of cheap SIP trunking:

• Poor Call Quality: Lower-priced providers may not invest in high-quality network infrastructure, leading to poor call quality and reliability issues.
• Limited Customer Support: Cheaper services often come with limited customer support, which can be costly in terms of downtime and lost productivity when issues arise.
• Lack of Scalability: Some low-cost providers may not offer the flexibility to easily scale your service as your business grows.
• Hidden Fees: Be wary of providers that offer very low base rates but then add numerous fees for features that other providers include as standard.

Maximizing the Benefits of SIP Trunking Through Smart Pricing Decisions

To truly leverage the benefits of SIP trunking, it’s essential to look beyond just the bottom line in your SIP trunk pricing comparison. Consider how the pricing structure aligns with your business needs and growth plans. A slightly higher upfront cost might lead to significant savings and improved communication capabilities in the long run.

The goal of switching to SIP trunking is not just to reduce costs but to enhance your business communications. Look for providers that offer transparent pricing, flexible plans, and the features that will support your business objectives.
