ABSTRACT:
The present invention enables a network to detect electrical interference caused by cellular phones and correct the problem by playing a network announcement to the network operator if the interference reaches a certain threshold level. In turn, the network operator will notify participants of the conference call of the interference and ask them to change the location of their cellular phones.
