The frequencies used by cordless phones are:
Channel Base Handset
1 46.610 49.670
2 46.630 49.845
3 46.670 49.860
4 46.710 49.770
5 46.730 49.875
6 46.770 49.830
7 46.830 49.890
8 46.870 49.930
9 46.930 49.990
10 46.970 49.970
Both side of a phone call can be heard on the base frequency, on the
handset frequency only the owner (or user) of the cordless phone can
be heard.
