Is SIP Trunking or PRI better for your Business?

PRIToday’s telecom market allows companies access to a numerous types of business phone systems, two of which are SIP Trunking and PRI. While some may consider the two indistinguishable, they have differences in terms of versatility, equipment, and cost.

What is PRI?

PRI is more of a traditional form of business phone system communications. It relies on the Public Switched Telephone Network and requires a circuit switch and physical phone line. Each line has 23 voice channels in order to handle simultaneous calls. You purchase additional connections per circuit of 23 channels at an additional cost. In other words, if you want to up your call capacity, you will have to install more lines.

What is SIP Trunking?

The biggest difference between PRI and SIP Trunking is that the former connects virtually to the aforementioned Public Switched Telephone Network. It routes all your VoIP calls through the Internet as opposed to through a physical line. Arguably the best thing about SIP Trunking is that you can combine data, voice, and video in one line and does not limit the amount of voice channels you can use.

SIP Trunking is also more cost efficient than PRI; SIP connections are sold as per call path. If you need to increase call volume you purchase more SIP Trunks (each one allows for 2-3 users).

Major Differences Between PRI and SIP Trunking

PRI requires you to pay per-minute fees if you want to make long distance phone calls. SIP Trunking, on the other hand, permits you unlimited local and long distance calls.


As mentioned, PRI requires a physical phone line with 23 voice channels. If you want to expand your business you have to install additional lines. SIP Trunking doesn’t require new hardware if you want to grow your business.


If you want additional features with PRI, you have to pay extra. SIP Trunking, however, has customizable features at no additional cost.

Our Conclusion

In terms of equipment, versatility, and cost, SIP Trunking is almost certainly the better choice for your business’s telecommunications. If you have any business phone system questions, please contact us. You can also follow us on LinkedIn.

How SIP Trunking Can Benefit Your Business

SIP Trunking works with VoIP by utilizing a SIP-based PBX that delivers telephone system services without a traditional analog phone line. Rather than a physical wire, a SIP Trunk acts as a ‘virtual’ line that uses a data circuit to connect to a network.  SIP Trunk also includes voice, video, and streaming media services, making this option ideal for businesses.

The lack of physical lines requiring maintenance with a SIP Trunk means that costs are considerably lower than traditional business phone service. SIP Trunking coupled with VoIP can save a company up to fifty percent on their monthly bill. SIP Trunking permits companies to only pay for the numbers they use rather than getting stuck in an agreement that includes excess analog lines. This results in companies being more efficient with the amount of resources they use.

Additional benefits of SIP Trunks include:

  • Inexpensive DID – A Direct Inward Dialing number, the number clients will use to reach a business on, costs less when purchased with a SIP Trunk. In the past, a DID is obtained directly from the phone company and charges were applied for the DID, IT and maintenance services, as well as the hardware associated with the system. A DID with SIP Trunking doesn’t include this infrastructure.
  • Better customer service– By adding additional geographical and international numbers, businesses allow customers more options when dialing in. With this barrier between a business and their customers lifted, sales will increase.         
  • Flexible locations – If a business changes office locations, they can still keep the same number because SIP Trunks are not bound to a physical location.
  • Flexibility– It is easy to add channels to your SIP trunk to cope with increased calls. A simple phone call will allow you to add channels, and often this can be done immediately.

Is SIP Trunking the Answer?

As you look forward to the new year you may be asking yourself how your business can simplify its phone management.  SIP trunking might be the answer you’re looking for!

You can spend significantly less time managing telecom issues and more time focusing on business because SIP Trunking will eliminate the need for installations and maintenance.

That Was Fast!

An SIP solution can be deployed within 30 to 60 days, or even a few weeks depending on the scope of the project. Because SIP trunking installation is handled behind the scenes by your SIP trunking provider, your business will be able to be up and running without any disruption to your business.

There is nothing additional to configure on your end, as long as you have a strong connection to the Internet and a SIP-compatible business phone system.   


Once you’re up and running, increasing capacity is as simple as contacting your provider. No more waiting on vendors to install cables, all you have to do is request additional trunks to scale your solution. Your SIP provider can also manage the network, disaster recovery and so much more!  

Remote Locations Are Seamless

With SIP trunking, you can integrate with local phone numbers to streamline interactions between employees across multiple locations. Remote locations can be added easily to the same network.  Everyone will have access to the same communication applications no matter their physical location!

Status Quo or Growing Like Weeds

It used to be a guessing game to forecast adding new lines in advance to prevent capacity issues.  I won’t even mention the investments made in time and money for physical space and installation management required to turn up additional lines.

With SIP trunking, call capacity can be increased on-demand to support unlimited calls. No more will you spend time installing additional lines when your business demands change.  Planning for future growth or overpaying for lines you may  or may not use is a thing of the past with SIP Trunking!



Why Businesses Chose SIP Trunking

What is SIP Trunking? Simply put, SIP Trunking combines your existing voice and data networks to improve communications. ESI SIP Trunking actually leverages your existing infrastructure if you are already using non-IP or digital PBX systems. It can actually slice your monthly phone bill in half!


Besides the cost savings, here are a few of the biggest reasons why businesses chose SIP Trunking:

Business Continuity

SIP Trunking features built-in redundancy. Why is this important? It ensures that your service will always be reliable and high-quality. In the event of a disaster, you can effortlessly route incoming calls to another location or to a mobile device.

Advanced Functionality and Easy Management

SIP trunking offers key features not found in analog systems. For example, you can make unlimited local and long-distance calls without fretting over the phone bill. SIP Trunking also supports bursting to manage peak call volumes. Additionally, you can add DID and caller name and number ID to efficiently handle calls.

Easily Expand and Transition

SIP adoption allows for transitioning to next generation technology. It can be simply expanded to hybrid or hosted PBX services. SIP Trunking also makes it easy to scale your connectivity requirements gradually, depending on what your business requires at the present moment.

A Company’s Role in SIP Trunking

16578936_sSIP Trunking offers a great deal of benefits. For businesses, SIP trunking can increase productivity, efficiency, mobility, and even save them money! However, making the switch necessitates businesses to take on a greater understanding of the technology if they want to reap all of the benefits. What role do businesses need to take in order to bring SIP Trunking into the office?

Security enhancement

The most important consideration when incorporating SIP trunking into your office is security. Businesses need to require complicated authentication procedures for all incoming and outgoing calls. This is especially vital when it comes to toll fraud, in which hackers attempt to get into your system to place international calls.

Assess Compatibility

If a company wishes to run SIP Trunking via the Internet, they need to take their bandwidth into account. If your network can not handle the different voice applications of SIP trunking, talk to Jay Faulconer with Advanced Communication Systems today to better understand what equipment and network you require to make the switch painless.

Understand the cost savings

Mr. Faulconer knows that SIP Trunking is a vast budget saver for businesses. As a matter of fact, companies can save up to 50 percent over their Primary Rate Interface (PRI) bill. The savings is made possible because carriers are switching to a singe, more simple rate for long distance calls. When this is coupled with the Ethernet access costs dropping, the savings for SIP Trunking really start to add up. In fact, we discovered that consumers tend to cut their existing business phone system services in half with SIP Trunking!
