Speech-capable Mobile devices’ most essential feature that we sometimes forget they have: Calling Services.

Voice Calls require resources from the network and the correct continuous interoperability of the device with the network, arrangement of codecs, ciphering, and many other logical, physical, and radio resources, to establish and maintain a voice call.

Testing is crucial for the correct performance of the device, evaluating the success rate of originated calls, incoming calls, alerting, and voice quality on both ends, requiring a variety of scenarios, and even though legacy technologies, still present failures, such as unexpected call drops turning into lower ARPU to mobile networks, and poor user experience.

The Supplementary Services supplements or modifies a calling service, such as number identification, call forwarding features to another number, when busy, when not available, call hold, call barring, and other scenarios, still an ongoing requirement that varies depending on the carrier, and shall be testing, delivering an expected behavior, while complying with the carrier certification tests.

We are ready to start testing your solution, performing all Calling scenarios, from Mobility, Handovers, Voice Codecs, Supplementary Services, and many other scenarios in more than +50 countries, under more than +160 mobile operators.

Let’s talk about your test plans and the required test your solution may need.
