Missed Call Alert (MCA /Slam Down)

Comsys offers a complete and extensive Missed Call Alert solution (also called Slam Down). This solution is for non-Voicemail customers and gives more call completion.
In most cases young,  Post Paid and Pre Paid customers do not make use of Voicemail. In some markets the use of Voicemail is just ‘not done’. In all cases the Missed Call Alert is a perfect solution: offering non-Voicemail customers the rich functionalities of call alert notifications.
The Comsys Missed Call Alert solution is based on the SpeechFrame Voicemail product. The solution can serve separate customer groups at the same time, each with specific settings i.e. pre-call (no charge) and single or multi SMS notifications. Comsys has also other Call Completion solutions.
