VoIP Termination Solution

Business Opportunity

Company XYZ is an established ISP provider with multiple points of presence (POPs) in country X. Currently the management is seeking to grow revenues with minimum capital expenditures. After conducting extensive research, the management decides to add VoIP termination services to it existing services portfolio.

VoIP Termination is an easy entry point to the VoIP market. The business model is based on establishing physical points of presence (POP) in several geographical areas and using them to transfer and terminate calls from VoIP to PSTN networks. Each POP is equipped with gateway(s), which receives VoIP calls in the form of data packets, converts them to analog signals and terminates calls locally to the PSTN network. VoIP termination typically appeals to ISPs with established POPs, entrepreneurs who want to enter the VoIP market, and VoIP carriers.

Before starting the business, XYZ's management conducts extensive research of alternative VoIP termination solutions. The research finds that different partners use different VoIP protocols as well as equipment from multiple vendors. The research concludes, that XYZ should look for a VoIP termination solution that could transparently transfer and terminate calls across VoIP networks based on different signaling protocols (e.g. SIP, H.323, MGCP). The other research finding is that the VoIP termination solution has to be scalable so that it can accommodate future business growth and at the same time be affordable to allow entry into the business with minimum capital outlays.

Business Solution

Although VoIP technology is much more advanced today than it used to be several years ago, VoIP implementations could still present significant challenges, especially to businesses without prior VoIP experience. VoIP termination providers face specific implementation difficulties as their equipment has to “speak” different signaling protocols, has to interface with other standards based VoIP equipment and consistently deliver high quality calls termination.

How Does The Solution Work?

1. The termination VoIP gateway receives call request from a VoIP origination gateway (owned by call origination partners)
2. The termination gateway sends authorization request to the RADIUS server
3. The RADIUS checks account balance with the Billing server and authorizes the call
4. The gateway connects the call to the PSTN network
5. During the call, the gateway converts data packets to voice signals and vice versa.

Upon call completion, the billing server records complete CDR information for the call that could be used for billing, reporting and analysis.
