TELCASTA is successfully scaling the international markets and helping telcos, carriers, MNOs & MVNOs to do business with advanced technologies. Our Business Support System (BSS) products extend converged & interconnect roaming solutions, rating, retail subscriber prepaid and postpaid billing, deal management, fraud management, and business process automation solutions. We provide Network Switching Subsystem (NSS) solutions through a complete product suite of Class 4 & 5 Switching solutions, Unified Communications, VoIP Telephony & Conference solutions.

In the last 20 years we have accumulated significant technical and commercial experience. During this time we have developed long-term relationships with a wide range of clients. These include FTSE 100 companies, high performance enterprises and progressive private sector organisations. All have the same vision, to use technology to enhance the way they do business.

Our customers include many of the world's largest carriers, rapidly-growing Consumer-VoIP operators, and leading mobile service providers who rely on us for their international voice traffic termination. We reduce their cost of transport and service support, while providing quality of service which is difficult to differentiate from the traditional phone networks.

We are based just in London, with our headquarters in West Drayton. We mainly serve clients throughout England, USA, Singapore, Malasiya, Dubai, India and Bangaladesh but with good travel links and remote working, we also work with a few select clients across the world

We tend not to specialise on vertical markets as the technology is vertically agnostic, but we happen to be particularly strong in Telecom.

Client relationships all start with a conversation. We then meet with you to discuss your plans or thoughts. We don’t send over shiny suited sales people. Instead, you talk over your requirements with our highly qualified principal consultants for free. If you want to keep the conversation going, we provide a quote for the next steps.

We never engage without you agreeing to the costs beforehand. We don’t ask you to sign long-term contracts and we tender for each piece of work we undertake to ensure that expectations and deliverables are agreed.
