ABSTRACT:
The present invention provides mechanisms for removing duplicate signals during a communication session. More particularly an over-air signal is received at a given endpoint and a stream of electronic data is monitored at the same endpoint for a duplicate to the over-air signal. If a duplicate is detected in the electronic data stream, it is removed so that only one occurrence of the signal is received at the endpoint.
