Maybe, you have heard many companies using a cost-saving tool named “SIP Trunking” to make calls over the distance. So what is SIP Trunking? and how does it work?
You may feel overwhelmed about those questions. But stay calm! Continue reading our article to know more.
What Is SIP Trunking?
In simple words, SIP Trunking is a “protocol” that you can use for virtual communications. It allows you to make and receive voice signals over the internet to anyone in the world.
SIP stands for “Session Initiation Protocol,” and “trunking” refers to a bundle of connections between users.
Nowadays, more and more people in the business world are using this protocol to conduct calls over the planet.
What Is SIP Trunking Used For?
As the above notes, the primary function of SIP Trunking is for communications. In detail, we can make a voice call with one other person. Not only limited by two person communication, but a conference call including multiple people is also allowed by SIP trunking. Furthermore, you can run video calls on this protocol.
Previously, with ISDN circuits, companies needed to physically install them in their locations which takes a lot of time and effort. Now, SIP trunking directly transfers voice signals over the data network, so we no longer need the copper lines which connect between locations.

In case you are still having ISDN, and considering new SIP trunking for your company. Here are reasons why you should switch to IP-based services right away:
With traditional methods of communication like the ISDN, many businesses, especially the ones with low intensity of call volume, could end up paying for the capacity that they never use.
Contrastly, you can accurately adjust the cost based on the actual usage when using SIP Trunking. Additionally, call centers with large call volumes could save even more money as they could cut down a huge amount of cost compared to the traditional methods.
A big advantage of SIP Trunking is that it allows you to contact anyone regardless of area. Besides, users can keep their numbers when moving to other countries. It means SIP Trunking is perfect for international companies having many branches over the world.
When globalization is increasingly occurring worldwide, having a way to connect globally means you are creating an advantage for your business. SIP Trunking is convenient as it allows you to use cloud-based services.
SIP Trunking unifies all methods of communication in one place, from texting, email to conferencing.
Besides, the installation is very simple. It could be finished within 2 days, and companies don’t require further infrastructure for the setup.

Who should Choose SIP Trunking?
With the aforementioned advantages, SIP Trunking is absolutely important in any business, especially companies with the below characteristics:
SIP Trunking systems require specialists to do the setup and maintenance. On the market, there are service providers who can help to do this job. However, you need at least a person having telephony knowledge to contact the service providers about any problems. This will save you lots of money as outsourcing everything from setup to maintenance could be very expensive.
SIP is cost-efficient, especially in businesses with a high volume of calls. For instance, sales or support call centers will effectively cut down costs when applying complex PBX systems supported by specialist high-volume SIP services.
If you belong to these types of companies, choosing the right SIP provider is extremely important in optimizing the cost. You should choose reputable providers and get the suitable capacity that fits your calling intensity. It will cost you more in the short term but result in overall savings in the long run.
How Much Does SIP Trunking Cost?
As we have mentioned, SIP Trunking varies in the price, depending on the call volume. But, overall, you may expect to pay 0$ to 150$ for the setup fee and 25$ to 50$ for monthly service.
Please note that each channel is used to receive or make a single call. So when all the channels are busy, you can not receive or make any other calls. Having more channels means you have to pay more. So choose the right number of channels for your company based on the call volume.
