What are Business SIP Trunks and Their Benefits?

Reduce Your Telco Costs with Business VoIP and SIP Trunks

In simple terms, business SIP trunks are the equivalent of business telephone lines and use the internet to make and receive calls. SIP or Session Initiation Protocol is a means of delivering telephone services over the internet. The technology is more commonly referred to as Business VoIP (voice over internet protocol).

A business SIP trunk is allocated a telephone number just like a normal telephone line. This number can either be ported in i.e. transferred from another type of service like a PSTN line, or a new number is allocated.

Replacement Technology for Traditional Telephone Lines

When a call is made using business VoIP, it travels via the internet to the IP Telephone Service Provider, which it turn delivers the call to the destination. That destination can be any type of telephone service including PSTN, ISDN, mobile phones or another SIP trunk.

The reverse also applies. When a call is made to the SIP trunk number, it travels to the IP Telephone Service Provider via whatever technology is being used i.e. pstn, isdn, mobile, etc., and is then delivered via the internet to the destination.

There are many benefits that business VoIP can deliver to a business with some of the major ones being flexibility and cost efficiency.

SIP Trunks Can Be Used Anywhere in the World

Business SIP trunks can be taken anywhere and are not restricted to geographical locations. You can take your IP phone or a soft phone (software loaded onto a laptop or smart device) anywhere in the world and as long as you can access an adequate broadband connection, it'll work like it would at the business premises. There are no more challenges with local exchanges, number portability and the need for telephone lines to be physically installed at the premises.

Business VoIP Is Cheaper

The other major benefit is cost efficiency. Business SIP trunks generally offer the best possible call rates and line rental charges across all telephone service technologies. They are the most cost efficient and easily deployable, and are regarded as the natural successor for the current PSTN and ISDN technologies.
