Like most companies, service providers want to identify the best way to keep costs down so as to maximize profits. One key element of priority is least cost routing as it helps to eliminate the added costs to communications that can eliminate a competitive edge.

RapidTel, a full-service Canadian telecom operator offers mobile calling, long distance, high speed DSL and local line phone service leveraging VoIP. To achieve a better competitive position, RapidTel turned to TransNexus (News - Alert) to help replace their outdated legacy softswitch, which had become too expensive to maintain.

One key goal for RapidTel was to be able to extend least cost routing solutions for their SIP providers. According to Sam Sharkawy, RapidTel lead engineer, the telecom’s goal was to move to 100 percent next generation SIP routing. TransNexus was a priority pick for RapidTel when it came time to select a migration partner.

As RapidTel sought to replace their legacy softswitch with redundant SIP proxies, the open source OpenSIPS SIP proxy was chosen. The solution offers the scalability and reliability necessary to meet RapidTel’s needs. TransNexus deployed the solution to deliver complete DID and SIP trunking services.

To allow for least cost routing and quality service routing, RapidTel was able to leverage the TransNexus Routing, Billing and Operations Support System (ROBSS). The telecom also enjoys fraud detection, number portability, traffic reports, billing, alarms and profitability analysis. In making this move, RapidTel increased its routing capabilities, billing solutions, and flexibility, while also realizing significant cost savings.

Today, RapidTel can now support least cost routing through a dynamic routing table of more than 50 million destinations to ensure each call route is optimized for profitability. More flexibility is also enabled with the TransNexus solution than the legacy softswitch.

“Overall, Our TransNexus solution brought our operating costs down tremendously,” said Joe DeSousa, president and owner of RapidTel, in a case study. “I would estimate that this software has saved us over 50-60 percent over our legacy costs.”

This technology has given us the opportunity to pass savings directly to our customers. Switching to a solution that we could deploy in the cloud entails huge savings for us in monthly recurring fees for hydropower and rack space,” added DeSousa.

By enabling RapidTel to extend least cost routing to its already strong base, the telecom operator can capture a larger share of the market, enjoying a more favorable competitive advantage.
