How SIP Trunks Could Save You Money

A lack of phone lines can have a negative impact on businesses.

If you’re unable to contact all the customers you need to and service them in a way that aligns with their expectations, you could lose custom. The long-term effects of this could include a loss of valuable opportunities, limiting of business growth, a loss of valuable opportunities and even wasting money.

So how can you mitigate the risk of this happening to your business?

Our SIP trunks are a fast, proven way to improve the scope of your business’ communications. Read below to discover how they could save your business money and maintain brand reputation.

What is SIP trunking?

SIP (Session Initiation Protocol) trunking is a way in which you can use your internet connection to make multiple concurrent calls. Our SIP trunks (also known as VoIP trunks) give you the opportunity to grow your business and reach a wider range of customers, while saving money in the long run.

SIP trunking offers virtual phone lines that sit within a fast IP network, which is connected to an IP PBX. All you require for this solution is a robust, quick internet connection.

Where businesses may have invested in ISDN as a way to increase their number of calls, nowadays that process is proving to be limited. We’ve outlined some of the reasons why below.

ISDN difficulties

The difficulty with ISDN comes down to several things. ISDN hardware can be difficult to install, and is very much an outdated way of making calls. ISDN requires more hardware than SIP trunking, which is more expensive and doesn’t offer the same benefits that SIP trunking does.

ISDN2 is a solution that only grants businesses access to two phone lines by which to make their calls. While ISDN30 offers 30 lines, the difficulty occurs when a business requires more than this. Say for instance you had a requirement for 35 lines or 40 lines, you’d need to invest in another ISDN30 connection and associated hardware.

You’d have 60 phone lines instead of your required 35 or 40, and you’d have spent more money than necessary. On the other hand, SIP trunks are infinitely scalable and range from 2 concurrent calls to any number, with a much more competitive price point depending on your requirement.
