I don't know what frequency DECT works on, but, two of my four
phone bases are DECT.

In the USA:
1920 to 1930 MHz.
5 channels, spaced 1.728 MHz apart.
4 mw average tx power. 100 mw maximum.

In the USA, there's no GAP support, which means that phones from
different manufactories not only will not talk with each other, but
also can interfere with each other. You might try your problem phone
with the other DECT phones and base turned off.
