Abstract
This invention relates to a communication apparatus which avoids interruption in the operation for an outgoing call of the first party from an extension telephone apparatus. In the case where there is conflict between an incoming call from the third party and an outgoing call from the first party in a selected unoccupied communication line, a call signal is transmitted to the all open extension telephone apparatus, at the same time, an other unoccupied communication line is automatically selected for the outgoing call. Accordingly, the conflict is avoided and the incoming call needs not be responded at the first party's telephone extension when a telephone number is being inputted, however, the fact that a call from the third party has been received is signaled on all open telephone extensions and can be answered there.
