2.4 GHz phones which are FHSS necessarily will not
let you set a channel, and will interfere with
WiFi equiptment.  Many phones just say "spread
spectrum", and some confusingly say DSS (for
"digital spread spectrum", not "direct sequence
spread spectrum); as far as I know these are
mostly all FHSS.  Analog phones presumably will
not be FHSS, and they will usually let you set the
channel.  Setting your WiFi channel to 1 or 11
will help, as will keeping WiFi equiptment as far
from the phone as possible and minizing the
phone's transmit power (I'm not sure if the phones
let you do that or not).

Please complain to the card manufacturer about
these problems!  My former company has been trying
to sell an inexpensive solution to this problem,
but manufacturers all claim that it doesn't add
value because nobody cares about these
interference issues.

Sorry for the self promotion, but you can read
