No feedback busy station
The Business Communications Manager VoIP gateway provides call progress tones in-band to the
user. If a busy station is contacted through the gateway, the gateway plays a busy tone to the user.
However, as NetMeeting does not support fastStart, no speech path is opened to the user before the
call connects. Because of this, the user on the NetMeeting station does not hear a busy signal from
the gateway.
