The purchase comes less than six months after the original deployment of VocalTec equipment and validates VocalTec's ability to quickly deploy solutions for high quality voice services. VocalTec solutions assist carriers in achieving a fast return on their investment, reducing capital and operational costs while maintaining the service quality and features of the PSTN (Public Switched Telephone Network) The worldwide voice telephone network.

Superior Voice Quality

The Data Access network has achieved excellent results on call quality control tests, including mean opinion scores (MOS (1) (Metal Oxide Semiconductor) See MOSFET.

). For the MOS test, which measures the quality of inbound and outbound voice traffic, the Indian telecommunications requirements stipulate a minimum score of four. Data Access outperformed TDM networks with a score of 4.6.

Minimal PDD Means High Call Quality

The implementation of extended overlap support enables VocalTec's packet telephony equipment to achieve the overlap functionality currently supported by PSTN switches. This minimizes PDD, enabling carriers running packet-based voice services to provide the highest level of call quality to their customers. PDD measures the time taken for a phone to ring after a number has been dialed. Data Access has a maximum PDD of three seconds for calls re-routed to avoid network congestion.

High Call Completion Rate Leads to Customer Satisfaction

The last test, call completion rate, defines the ratio of calls completed to the number of call attempts notwithstanding complications such as network congestion, no dial tone, busy signal, or if a subscriber hangs-up after dialing a wrong number. Data Access has a success rate of 62 percent, a score that outperforms the results of other Indian telecommunications providers.
