Your business is directly linked to the quality of service and the efficiency of your telephone calls. REGLIS is a powerful Call Monitoring System providing a complete analysis of incoming and outgoing traffic taking into account your telecommunication infrastructure capabilities. Designed for telecommunication operators and network managers, REGLIS allows you to quantify and qualify the telecommunication traffic that occurs on your telecommunication infrastructure taking into account its specifities (number and type of ISDN links, specialisation, size ….). The quantification process provides a complete status of the incoming and outgoing traffic based on a daily, weekly or monthly analysis. This report is mandatory to check the compliance between the customer needs and the telecommunication operator offer. The qualification provides a detailed analysis of the telecommunication traffic according to several criteria as : call origin and destinations (Country / Areas ), services used (voice / data), called numbers, hourly details of incoming and outgoing calls, and efficiency evaluation of incoming and outgoing calls. The REGLIS analysis provides a clear and deep analysis of the traffic issued from the customer premises in order to optimise its telecommunications infrastructure according to technical and human means. REGLIS lays the emphasis upon on the possible dysfunctions and justifies the telecommunication infrastructure evolution proposals as they are based on rational criteria issued from a real measurement campaign. Various telecommunication operators are using the REGLIS solution in order to comply with the QOS measurement obligation they have to provide to the regulation authority according to the ETSI ETR 138 standard. The combined solution of the probes WAVETEL ACTRIS with the REGLIS software allows you to store and survey your telecommunication traffic day and night.
