Push to talk (PTT)
The DP Handsets support the push-to-talk (PTT) features which is a technology based on the instantaneous communication commonly employed in wireless cellular phone services using a button to switch the device from voice transmission mode to voice reception mode. This feature is similar to the “walkie-talkie” used and the PTT mode switches a phone from full duplex mode, where both parties can hear each other simultaneously, to half duplex mode, where only one party can speak at one time. Multiple parties to the conversation may also be included.
- Users could press and hold the Push-to-talk key from any screen to quickly initiate a PTT call.
2. Available handsets (subscribed to the same base station) will receive the PTT call.
3. Keep holding the PTT key while speaking.
The channel status will change to Sending PTT to indicate that you are transmitting as displayed on the following screenshot.
To terminate PTT call, press button.
The PTT feature is always enabled on the base station, to use this feature, users need to enable the PTT on the handset at: Handset Menu → Preferences → PTT → set “Enabled”.
Also, to use PTT, the DP722 needs a dedicated button to push and then to talk, user can choose to use either LSK (Left Softkey) or RSK (Right Softkey) in Shortcuts settings. (If you forgot to enable the PTT, when you press the PTT softkey, it will redirect you to the setting to enable it before you can use it.)
Users can configure the “DECT PTT Silence Timer” on the Web UI at → DECT → General Settings. When a PTT call is established, any handset that enabled the PTT feature will automatically join the PTT call. if there is no one talking, after a certain time, the PTT call will be closed. This timeout setting is to determine how long the PTT call will be closed after being idle status. If set to 0, the timer will be disabled, and the PTT will remain forever until all parties exit the PTT call.
