ITSPs provide digital telecommunications services over the Internet using Voice over Internet Protocol (VoIP). In many cases, ITSPs provide services directly to end users or as wholesaling suppliers to other ITSPs. Many ITSPs use signaling and multimedia protocols, such as the Session Initiation Protocol (SIP), the Media Gateway Control Protocol (MGCP), Megaco, and the H.323 protocol. One of the earliest VoIP protocols, H.323 is slowly declining in popularity and is rarely used in consumer products.

In an ITSP, a customer can connect via a local area network to the provider's network via a traditional analog telephone set, an IP phone, or a private branch exchange (PBX) system via a media gateway to the provider's network. ITSPs are also known as voice service providers (VSP).

There are three main components required to set up your own ITSP:

1. Hardware Infrastructure
2. Software
3. Telecom carries / gateways

Hardware Infrastructure

Hardware infrastructure can include dedicated servers, switches, routers, internet bandwidth, etc. Hardware infrastructure can be rented from a third-party provider or owned by your company.

Software

You can use the portal to offer cloud-based / hosted ICT services to your customers and separate their billing and accounts. It has two main components, first, your main marketing website with products listing as well as a self-service customer portal and eCommerce functionality, and second, a white-labeled multi-tenant ICT service portal.

Telecom carries / gateways

These carriers include VoIP/SMPP/SMTP/PSTN carriers for voice terminations, SMS/SMPP carriers for SMS messages, and email gateways. It is essential that the admin select a VOIP/PSTN/SMPP provider that can originate and terminate bulk calls.
