The Speedphone 10, costing 39 euros in Telekom, is now the latest model and is recommended for the Speedport W 724V. However, it also runs on all models that have a DECT part, can of course be used from the Speedport W 723V and the W 921V. The CATiq 2.0 support ensures that the router-based functions can be used. Before I go on, first to the device itself.
The build quality is optimal, one might think that Telekom has drawn on their very good hardware early 90s. The same applies to the charging cradle, however, have to be careful that the phone does not fall over, because it sure is not it unfortunately. Slightly touched it falls already at the back, annoying. What it does offer a loud and good sound quality with minimal noise, a contrast display with good viewing angle, and simple operation, as well as HD Voice. The latter can of course only be used if you call a subscriber with IP port and HD tauglichem terminal which are all Speed Phones. It only requires two AAA batteries, the models Speedphone 100 and 500 needed three of them. Be careful when loading, because one wants to conserve the batteries, does not overload you better. All Phones Speed and even almost all cordless phones with AA or AAA batteries namely have no charge-'Endabschaltung. Therefore, the battery is constantly overloaded gently, which reduces the time the endurance.
Consider the software, it is somewhat reminiscent of the Speedphone 100: Rudimentary functions and limited to essentials, but with significantly aufgeräumterem menu. The internal phone book does not exist, it is therefore quangsweise the router phonebook used which facilitates the clarity. Beautiful is also that unlike all other Speed Phones also each allocated a number of own ringtone can be donated here. One uses for example a home number, and one for the office, a ringtone can be separately set for both. Is a bit annoying that the contact specific assignment of call tones when Speedphone 10 is eliminated. The additional functions, email and RSS feed, which offers the Speedphone 500, there is also not what it functionally to the level of Speedphone is 100. Why not offer an extended version, like so many inconsistencies not obvious in the telecom routers.
Conclusion: Aside from the lack of additional functions, this model excels through ease of use, contemporary ring tones and rugged housing. For the price you can not complain absolutely, only criticism would be the somewhat loose seat in the charging cradle. Through firmware update features, you can also expand or optimize, might happen in this direction still something.
