Becoming an Internet telephony service provider via the use of asterisk based business solutions: a layman’s guide

An Internet telephony service provider (ITSP) provides Voice over Internet Protocol (VoIP) and digital telecommunications services to either residential or commercial enterprises. Digital telecom services eliminate the costs associated with traditional phone services and allow individuals or companies to make substantial cost savings with no loss of quality. With a general knowledge of ICT, it is a relatively straightforward manner to set up in business as an ITSP. At each stage of the process, other services exist to enable the correct management of your telecommunications business. A common benefit cited by ITSPs for the selection of this business model is the scalable nature of the service and how it allows an enterprise to build their business free from the traditional high capital expenditure costs of ownership that other telephony solutions would entail.

Stages to Consider when setting up as an ITSP

There are three stages to consider when setting up as an ITSP. These are the choices over which VoIP platform or switch to using, which VoIP carrier to chose, and the selection of end-user equipment. These decisions are all explained in more detail below. Furthermore, information is given on a number of suppliers at each stage to enable the potential ITSP to make an informed decision.

    1. What does VoIP Platform or Switch do?

Firstly, you will require a VoIP platform or switch. This platform provides the class five features for your service. Class five includes features such as voicemail, hunt groups, and call-forwarding. A number of companies who offer VoIP platforms are reviewed below to assist in the selection of this first stage in becoming an Internet telephony service provider.

    1. Why is VoIP Carrier important?

The next requirement to establish as an ITSP is to engage a VoIP carrier. This is known as a class four service. Considerations to make when selecting a VoIP carrier are coverage and origination. For this reason, it is important to check the footprint of a particular carrier in your target market before engaging their services. Factors such as quality and the availability of support should also be given careful thought before any decision is taken. Many companies will offer automated support as part of a free package and some companies even offer free support from human operators. With a large number of VoIP carriers in the market, it is worth spending some time comparing the features and support packages that come as standard.

    1. Selecting End User Equipment

The final requirement is the choice of end-user equipment or software. Some ITSPs may prefer to allow the client to use their own equipment whereas others provide this directly. Using an analog telephone adapter (ATA) allows existing equipment to be used in the ITSP system within substantial additional costs. Alternatively, an IP phone is a popular choice that gives access to the class five features directly from the phone unit.
