Have you tried unplugging the A/C on the phones? You may need a line conditioner or better ground to eliminate this. Are your phone plugs 3 prong? Try a cheater (3 prong to 2 prong adaptor) to avoid ground loops. Your phone system may be grounding itself in the same place as your electricity???
Even relocating the phone bases to the other side of the house to utilize circuits on the other side of you fuse box may do the trick.
My electrician would be lost if you called him with this problem...
