For a Siemens device is not really good

We have in our law firm about 40 analog corded phones in use, and have been for years. Since we use a software solution to make phone calls, we do not require expensive system telephones and a good analog phone is quite enough.

As more analog desktop phones are becoming less available, I got somewhat reluctantly a few of these Siemens phones 1-2 years ago. Reluctantly, because I know the poor quality of Siemens DECT phones and because I do not like this rubber Schwabbeltasten relatively high pressure required.

My experience in short form (for now about 1-2 years):

Positives:
+ No battery
+ No power supply
+ Relatively compact
+ Bearable Design

Negatives:
- Wabbel rubber keys without plastic cover
- Relatively large pressure to select required (difficult a brisk, error-free dialing by hand)
- When 2 phones listeners were broken, was reflected in the fact that could be heard (such as one from a dimmer interspersed in the line noise) in the listener a humming. With a handset exchange wandered the problem with the next phone. After all, Siemens has replaced the phones without complaint and since all phones OK.
- Irregular (on average every couple of months) is falling from a telephone. Our telephone system ("Agfeo AS 200IT") thinks then, on the phone the handset is lifted. For the employee, the phone is simply "dead". Only remedy is to push the Lauthörtaste and wait until you hear the dial tone, and then hang up in this case. Strange error. Incidentally, some phones guidance was already in the box, which suggested this procedure for commissioning.
- The phone can indeed extract clip, but not the time of the Clip Info. Embarrassing. So you have to constantly adjust it, because terribly exactly the internal clock is not. If you at least could simply turn them off, the internal clock.
- The R-key, actually the most important button on the phone for commercial use is completely unobtrusive hidden in other keys.

Conclusion:
There used to be much better phones for much less money. That Siemens * the * expert in phones was once a sad picture that Siemens offers here.
