SIP Trunking: Everything You Need to Know

SIP trunking

SIP trunking is becoming the new business communication standard. From small businesses to large corporations, everyone can use SIP trunks to generate better and more reliable communication channels. So, how can your business benefit from this service and why should you consider investing in it? Here we will cover everything you need to know about how SIP trunking works and how it can revolutionize the way your business communicates.

SIP Trunking: The Basics

Before Session Initiation Protocol (SIP) or Voice over Internet Protocol (VoIP) technology, phone calls were carried out through public switched network (PSTN) only. Such a network requires tangible, physical connections between two points to make and answer calls and to connect two parties. SIP, however, uses virtual phone lines instead. This gives users the ability to place calls over the internet to anyone located anywhere in the world.

How Does SIP Trunking Work?

Session Initiation Protocol (SIP) sends or transmits voice, video, and unified communications over an internet connection. SIP trunks break down voice signals into digital packets and then transmits these packets to a destination. This is called a packet switch network.

A SIP trunk can hold multiple SIP channels. Each channel is equal to one inbound or outbound call. Having multiple SIP channels means that users can make and answer multiple calls at a time through just one SIP trunk. They will not need to invest in more than one phone line.

SIP technology will work alongside your office’s IP-enabled PBX system and will replace traditional phone lines. Doing so, it can convert your office phone system into one that can effectively support internal as well as external communication.

SIP versus VoIP

Although SIP and VoIP terminology are often used interchangeably, they are not exactly the same. It is true, however, that both types of technology help businesses make and answer calls over the internet. But how can you distinguish between the two?

Voice over IP achieves the most basic virtual communication feature. That is, it uses the internet to digitally transmit voice to a destination. For the most part, VoIP is limited to voice transmissions. VoIP providers often allot unlimited minutes with certain plans to ensure you get the most of the service.

SIP, on the other hand, builds off of VoIP to provide and manage multimedia communication such as voice and video. In other words, it defines messages transmitted between two parties. And so, SIP enables video messaging, conferencing, text messaging, and file-sharing. With SIP trunking, you benefit from an all-inclusive business phone solution. With SIP and VoIP working together, your business will benefit from cost-savings and increase productivity and efficiency.

Advantages of Using SIP for Business

So, why are more and more businesses paying attention to SIP and voice over IP technology to improve communications? It is because along with better internal and external communication models, these systems come cheaper and with various telephony features. Here are some reasons why you should use SIP for business:

1. Affordability and Flexibility — Since SIP calls are routed over the internet and not traditional phone lines, your business can make calls to anyone in the world. You are not limited to local calls only. And so, your business has the opportunity to connect with long-distance and international customers without paying high international fees. Instead, you will pay what you subscribe to with your SIP provider. Read our article on SIP trunk pricing for more information.

2. Unlimited SIP Channels — A SIP trunk holds an unlimited number of SIP channels. This makes it so that your business needs only one trunk, irrespective of how many calls occur simultaneously. How many channels your business could use will depend on your calling needs and logs.

3. Access to Advanced Communication Features — SIP will boost your office communication system by giving you access to more virtual communication features such as video conferencing, SMS (instant messaging), voicemail, call management, and more. These features and services will strengthen your office communication system so that you can provide better service to your customers and contacts.

4. All Communication in One Place — Lastly, SIP trunking enables you to handle and manage all your communication needs in one place. You won’t need to subscribe to additional services or programs. This, too, helps you save time and money.
