Ok,  Phones that utilize DSSS (digital sequencing spread spectrum)
modulation method that are not in the 2.4GHz range will be your best bet.
This is most of the current 5.8GHz phones and some of the old 900MHz phones.
A lot of the old 900Mhz phones were either analogue or FHSS (frequency
hopping spread spectrum) and are prone to pops and clicks from the
environment or a poor implementation of FHSS.  In theory a FHSS and a DSSS
should be able to coexist in the same frequency spread (radio band) such as
a 2.4GHz FHSS phone and a 802.11b WAP (specified as a 2.4GHz DSSS data
system).  In practice this coexistence is marginal at best.

Probably the best solution to this would be for the WAP and Phone
manufacturers to get together to integrate phone and data out of the same
WAP(VOIP anybody?).  Second would be for all phones to move to 5.8 and all
data to 2.4 (I can dream can't I?).  There is some development in the works
and there are some new Cisco rumors but it won't be priced for the home for
a long time.
