We want to tell you about the pros and cons of the service so you can make the best decision for your organization.

By the end of this article, you will know what SIP Trunking is as well as the pros and cons of the service. This will help you decide if SIP Trunking is a good fit for your organization so you can make a more informed buying decision.

What is SIP Trunking?

Session Initiation Protocol (SIP) allows you to run your phone system over the internet rather than a traditional phone line. Trunking serves as the backbone of phone lines used by many users which connect to a telephone network.

The main objective of SIP Trunking is to bring a standard PBX phone system to the cloud. This allows you to achieve lower costs and the scalability of a cloud-based phone system while utilizing your existing PBX system.

SIP may also be used as part of your unified communications allowing you to synchronize your communication channels improving productivity and efficiency.

Pros and cons of SIP Trunking

There are pros and cons to just about any product or service. SIP Trunking is no exception.

While SIP Trunking is a more updated service and utilizes a new way of using voice, there are still pros and cons to using the service.

Finding out the benefits and challenges of SIP Trunking will help you determine if it is a good fit for your organization.

Pros of SIP Trunking

There are a few advantages that SIP Trunking can bring to an organization. The pros of SIP Trunking include customizability, low cost, and better scalability.

●      Customizability

A major benefit of SIP Trunking is the ability to customize your service to your organization’s needs. This is something that you can’t do if you were to purchase another form of hosted service.

Since SIP Trunking is highly customizable, you can control things like security options and upgrade options without the need for vendor involvement. This allows you to choose options best fit for your organization’s needs.

●      Low cost

The cost of SIP Trunking varies on different factors. Since SIP Trunking is so customizable, your cost will vary based on the variety of options you will have when it comes to what you want out of your service.

However, even though the cost of SIP will vary based on the custom features you select, SIP Trunking is still typically cheaper than other alternatives. In fact, SIP Trunking can reduce your monthly phone bill by an average of 50%.

Because SIP Trunking is virtual, there is no physical infrastructure that needs to be maintained. With alternatives that require physical infrastructure, there are typically maintenance costs.

Since SIP Trunking enables you to make calls over the internet, which your company is already paying for, you will not have to pay for separate voice calls.

●      Better scalability

Traditional phone systems limit your organization’s ability to add or subtract phones. Adding phones to a traditional phone system is both expensive and time-consuming since each phone requires a connection to a copper line.

With SIP Trunking, there is little equipment and the phones connect via the internet allowing you to add or subtract phones much easier than traditional phone lines.

Cons of SIP Trunking

The cons of SIP Trunking include compatibility issues and bandwidth issues.

●      Compatibility issue

Not every phone system integrates properly with SIP Trunking. If your phone system is outdated, it may not be compatible with SIP Trunking and you may have to invest in a new phone system before switching to SIP Trunking.

●      Bandwidth issue

SIP Trunking allows you to rely on one network since your phones connect to the internet. You do not have to manage and pay for a voice network and internet network when it comes to SIP Trunking.

However, this may result in bandwidth issues. Making sure you have a reliable connection to the internet and enough bandwidth to supply both your internet and voice is important in making sure your SIP Trunking and internet browsing are as efficient as possible.

If you are using too much bandwidth on your network, it could result in latency issues. Latency issues could look like slow load page times while browsing the internet or call breakups and drops.
