PTT Button vs Call Button Feature
By default, when the PTT button on an Intercom is pressed, the Intercom’s microphone is
turned on and the audio is transmitted to TalkMaster™. TalkMaster receives the audio,
records it, places an entry in the Calls Waiting Queue and sends the "Your call is being
connected" message to the intercom. If desired, the TalkMaster operator can play the audio
back by double-clicking the entry in the Calls Waiting Queue. When the TalkMaster operator
activates the Listen button, the Intercom’s microphone automatically switches on so the
Intercom user can operate in Hands Free mode.
When the Call Button feature is enabled for an intercom, the PTT button’s function is changed
to a Call button. When the Call button is pressed, a short signal is transmitted to TalkMaster.
TalkMaster receives the signal, places an entry in the Calls Waiting Queue and sends a signal
to play a two tone beep on the Intercom. No audio is captured in the Calls Waiting Queue
using this option. When the TalkMaster operator activates the Listen button, the Intercom’s
microphone automatically switches on so the Intercom user can operate in Hands Free mode.
Intercoms in Call Button mode play a two-tone beep whenever they connect to TalkMaster.
The Call Button feature has been implemented for customers who are not able to support
multiple concurrent audio connections due to low bandwidth TCP/IP connections. It can also
