In a telecommunications system (100), a method and apparatus for buffering
the initial speech of an initial speaker in a push-to-talk call is
disclosed. The method includes the steps of determining at least one
participant or group to call (410, 510), sending a call request to the at
least one participant or group (520), determining if the at least one
participant or group is registered with the telecommunications system,
notifying the initial speaker to begin speaking after determining at
least one participant is registered with the telecommunications system
but prior to connecting all called parties, receiving and digitizing
voice packets from the initial speaker, storing the digitized data
packets in a storage medium and transmitting the digitized voice packets
when a predetermined packet transmission triggering event occurs. The
apparatus for buffering the initial speech burst of an initial speaker in
a call includes a first server (140) and a second server (150)
communicatively connected to the first server. The second server is
programmed to execute the steps of the method described above.
