| The T65 was a formidable phone. Very good audio too.

| which are within the official tolerances of the time for the
| local market but outside tolerances for US standards (digital
| pulse dialing phones are usually within spec for both because
| the tolerance ranges overlap).

| The timings of the phone's rotaty dial might be off. Allegedly
| FritzBoxes are rather conservative when it comes to these
| timings.

| pulse to tone converter solved the problem.
|
| Btw, in case pulse dialing works with a FritzBox one can dial #
| via hook flash. This allows to dial the internal numbers [0].
