A telephony communication device is capable, upon an election by a user,
of transmitting a defer answer signal in response to receiving
notification of an incoming call. The defer answer signal causes the
telephony infrastructure equipment to place the calling party on hold and
play a voice message to the calling party requesting that the party
remain on hold and preferably informing the calling party that the called
party will be able to accept the call within a predetermined time. Upon
the called party becoming available to accept the incoming call, the
called party retrieves the waiting call by sending a connect call signal
from subscriber's communication device.
