DECT phones getting static

[Wesman8678]

I hope someone can help me. I have a TDE200 and I'm using 20 KX-TD7696 wireless DECT phones with 8 KX-TDA0158 (8 channel DECT cell Stations) When I'm on a call it will start clear and then get major static for about 3 seconds and then clear up again. This is happening on every phone and on every Cell station.
