In a standard two‑way call in Zenitel Connect Pro, Zenitel intercom devices communicate in open duplex mode, enabling natural, hands‑free conversation with automatic echo cancellation.
For situations where controlled, one‑way speech is preferred, Zenitel native devices support Press‑to‑Talk (PTT), allowing users to momentarily override open duplex mode.
Press-to-Talk Operation
- Press M key
- Device enters Talk Mode
- Loudspeaker is muted
- The device sends DTMF ‘*’ to the remote side
- Release M key
- Device returns to Open Duplex
- The device sends DTMF ‘#’ to the remote side
The Zenitel Connect Pro will relay these DTMF * and # events to the remote device.
Remote Control of Speech Mode (Received DTMF)
Zenitel native devices respond to DTMF signals received from the remote device:
- On receiving DTMF ‘*’
- Device enters Listen Mode
- Microphone is muted
- On receiving DTMF ‘#’
- Device returns to Open Duplex
Configuration Requirements
No additional configuration is required for Press‑to‑Talk functionality. However, this feature only applies when at least one device in the call is a Zenitel native device. If neither device in the call is Zenitel native, Press‑to‑Talk does not apply.
