IP based phone services have introduced ways to modernise business phone systems and help businesses leverage cost savings from reducing the need to rely on traditional phone technology and services.

Despite these benefits, there is still some hesitance from both business owners and employees to switch to an entirely IP based phone service from their current system.

For those who are still unsure about making the change, a great option that still brings with it the benefit of cost savings is SIP Trunking.

This allows you to leverage the benefits offered by IP based phone services whilst still having renting lines on the traditional PSTN (public switched telephone network).

What Are SIP Trunks?

SIP Trunking is an alternative to traditional phone services that allows your PBX (private branch exchange) to make use of an internet connection to receive and place calls.

SIP (Session Initiation Protocol) refers to the standard of data encoding, whereas ‘trunking’ refers to the type of connection. SIP encoding isn’t just limited to voice calls, but include faxing and unified communications tools such as instant messaging and video.

SIP Trunking allows voice data to be delivered digitally rather through traditional analogue means via copper lines.

This mean that when a call is received or placed, SIP Trunking will take that call and turn it into data so that it can be sent or received over the internet as ‘packets’.

How Does SIP Trunking Benefit My Business?

We know now that SIP Trunking allows voice to be sent as data over the internet.

Cutting Costs

Where does the cost saving benefits factor in?

As an example, let us assume your business is currently paying for 4 lines on the PSTN. This means only 4 calls can be made or received concurrently.

You may have some busy periods where this happens, but the likelihood of all these lines being in use all day for both incoming and outgoing calls is unlikely.

As you currently have 4 lines on the PSTN, you will be paying your line rental fee (per line) as well as the cost of calls made.

If you ever only have 2 out of the 4 lines in concurrent use, you could replace 2 of these with SIP trunks to be used for outgoing calls and to reduce your line rental costs. Depending on your provider, there may be a reduction in costs per call as well

If during the course of your business growth you determine the need for more lines, the technology allows for scalability and reducing the need to install or pay for additional physical lines on the PSTN.

Being IP based, your provider will be able to provide you with additional SIP Trunks as required.

There is no risk of losing the ability to make outgoing calls if your internet connection goes down, as you will still have the use of your PSTN lines.

Using SIP Trunks will allow you to reduce costs and operate your business phone system in a more efficient and modern way.

Many businesses have found making use of SIP Trunking have helped cut the cost of their line rentals in half.
