SIP Trunks: Why You Need Them In VoIP


Why Are SIP Trunks Needed in VoIP?

Phone lines are inefficient, outdated and expensive. But VoIP still requires the right infrastructure to guarantee high-quality communications. That’s where SIP trunking comes in! 

When a business invests in an IP phone system with accompanying data network support for transmission of voice traffic over Internet Protocol networks such as DSL or Cable Modems, they also need to invest time and money into ensuring that connectivity is always available so their employees can communicate when necessary – even if there was no physical telephone line installed on-premises at all. 

This means investing heavily not just into Quality Voice (i.e., how clear your calls sound) but also Quality Connectivity (i.e., how much lag you experience while conversing).

What are SIP trunks, and why are they so important when it comes to VoIP? If you want your communications to be clear from end-to-end no matter what the distance is between different points in a network, then look into getting yourself some of these beauties!

What is SIP Trunking and How Does it Relate to VoIP? 

Communications technology is full of industry terminology that you’ll need to be familiar with as you get started. Here are a few of those terms we feel are worth knowing:


Many people are looking to get their hands on the newest, coolest tech out there. Voice over Internet protocol isn’t new by any means but it’s seen massive growth in recent years because of how accessible and easy-to-use this technology is online. VoIP encompasses many different types of equipment that can be used for business calls or just chatting with friends; voice data transmitted through IP networks rather than traditional phone lines make things much simpler for both parties involved!


The world’s most advanced enterprise-grade telephone system is the best way to communicate in an office, no matter how many people you need.

Hosted VoIP

VoIP is a user-friendly communication system that your provider hosts on their own equipment before delivering it over the internet to you. The receiver of this service does not need to maintain any equipment in-house for these VoIP services.

SIP Trunking 

VoIP is a telecommunications service that allows people to make voice calls over the internet. It connects your business phone system with a VoIP provider and lets you use on-site hardware for making or receiving long-distance, video chats, and even some Internet browsing!

The term “trunking” comes from an era when communication was mainly analogue. Nowadays, SIP trunking uses digital “wires,” and businesses can add additional channels without the need to invest in costly physical infrastructure.

What are the Differences Between a SIP Trunk and a SIP Channel 

Trunks and channels are not interchangeable, which is why there has been a lot of confusion about SIP pricing. A trunk connects your business’s phone system to external networks while a channel allows for incoming or outgoing calls. 

Think of the former as tunnels on highways that connect one place with another, whereas lanes represent opportunities to drive in either direction. This means companies only need one single-lane tunnel per organization in order to handle multiple simultaneous conversations at once—which explains why vendors charge based on how many channels an individual company uses when it comes time to pay up!

What are the Advantages of SIP Trunking along with VoIP for your Business? 

With hosted VoIP, businesses can save time and money by not having to maintain their own software. They also get access to extra features like PBX that are offered as well! So why would anybody choose SIP trunking over a hosted VoIP solution?

  • Control – The VoIP system will be the perfect fit for your company because you have complete control over its configuration.
  • Cost – You should invest in SIP trunking because the cost per call is significantly lower. If you are a company that deals with high volumes or international communications, this could be your ideal option!
  • Simplicity – This is why SIP trunking has become popular. You can combine your phone lines and internet data into one network, saving money on costly equipment.
  • Scalability – You can have as many channels in your trunk as you want. Adding extra lines is easy because it doesn’t require any physical setup!
  • Security – You can have as many channels in your trunk as you want, and because it doesn’t require any physical setup, adding extra lines is easy.

SIP Trunking vs. PRI 

The Primary Rate Interface (PRI) is an important difference between VoIP and SIP. PRI offers significant advantages for any business, but especially those with older telephone systems or who want to remain connected during network outages. If you’ve been researching phone options then it’s likely that the terms “VoIP” and “SIP” have crossed your path before – this article will discuss how they compare in more detail so that you can make an educated decision about which one suits your needs best!

Expected Costs of SIP Trunking 

The total cost of SIP adoption varies between businesses but is almost always a favourable amount compared to that of traditional communication systems. Some of the charges you will avoid may include:

  • Costs of incoming phone lines
  • Long-distance charges
  • Maintenance fees
  • Usual higher costs of older technology

SIP Trunking typically comes in 2 different types of pricing options: pay-as-you-go service where an end-user would pay for all usage, or a session-based offering where certain usage/call types are included. Typically there are additional costs outside of the cost to use SIP trunking including IP PBX and enterprise software licensing as well as maintenance fees associated with these solutions.
