Uniden 2.4Ghz Cordless Phone usage causes dropped.... I have searched high and low to find out how

Question

I have searched high and low to find out how to get my MN- 700 Wireless-G Base to stop dropping signals when any of my Uniden 2.4Ghz phones are used.  I tried changing the channel on the phones - nothing.  I tried changing the default channel in the Network software that came with the Wireless unit - nothing ... are there any instructions that can help me solve this problem as it is becoming difficult to continue working.   thanks.
