Portable Telephone Coaching Equipment

You are Welcome...

Are you a communication trainer? Are you a company that offers telephone training? Then you are right with us! We have been building 'phonecases' since 1998 and in 2013 we were the first provider on the market to implement an Android tablet into our 'phone cases' for control purposes.

S, M, XL MODELS 2024 also with 5G and HD Technology

Now NEW the XL Model 12 and Model 12+1 !!
This unique device on the market opens up new horizons for you. Highly efficient telephone training with up to 6 couples (12 delegates) at the same time. All 12 delegates receive their handsets at the beginning of the training, no more passing the handsets back and forth, saving valuable time so that they can learn significantly more content effectively. With 12+1 the trainer has his own handset, optionally with a headset.

As usual, automatic recordings, and everything at the same time! With our new software in the 8" tablet, the trainer has a complete overview, can join the calls as desired and listen to everything out loud or with a headset. The Maxi model has many extras. For example the handset function "LISTEN MYSELF", "LISTEN the OTHER", "LISTEN ONLINE", 3 way CONFERENCE and, and,...Please ask for more informations.


The S models with two Gigaset or two Grandstream HD telephones, Lenovo 8" tablet, BT 5W speakers in a handy mini case are still available with the standard software.

The robust M model is well suited where there are requirements for safe transport (e.g. flight luggage). It also differs with the placement of the two handsets. The lid is removable on this model.

The S, M and XLi 'phonecases' are modular, consisting of just 5 branded products built into a proper case for safe and convenient transport or shipping. All electronic parts in the case are always up to date on the market. The modules are linked to our TTS software (TelephoneTrainingSoftware). In principle, it is a unique software solution for creating the telephone connection (telephone exchange), automatic recording and controlled playback of the conversation and file management that we offer here. There are also many other functions.

Your advantage with our product:

Thanks to our latest technology, the operation is wireless, automatic and very easy to use. The tablet, the speaker and the phones work using powerful batteries that only need to be recharged at the end of a training day. No other product of this type available on the market offers this level of comfort for trainers to move freely with the tablet and easily control everything. The powerful loud speaker can also be optimally positioned as desired, regardless of the phonecase. Any seminar room audio system can also be linked. The phonecase itself largely remains in the background during training. It is placed anywhere in the room near a socket and only connected to the 230V power supply.

The dimensions shows the image. The weight of the phone cases is S=3.4kg, M=4.5kg and XL=9.5kg. This makes our 'phone cases' ideal where functionality, dimensions, weight, transportability and price are the trainer's focus.

The videos on the side gives you an first impression of how the system is operated.
