Serviced Assurance monitoring through managed service.

Operators should be able to measure the QoS of each interconnection route, by measuring the CLI success rate for calls, in order to optimize the route selection. Operators want to check whether the SLA signed with its interconnection partners is fulfilled or not. A simple and effective way to have a good estimation of the Quality of Service offered by the interconnection carriers is to check if the CLI is transmitted to the target parties.

Carriers keep looking for a managed service that would make calls to different destination networks using predefined routes and check the CLI on the receiving party as well as report on the CLI successful rate for each route.

CLI Checking from GOTEL Telecom helps carriers control the quality and delivery of many services like CLI, MOS, and False Answer. This solution enables carriers to set up automatic calls to over 500 mobile networks worldwide and the increasing number of fixed network operators.
