Site comms that survive gloves, noise and a dropped phone

Trades, plant operators and the site office on one channel, on whatever hardware the site already issues — including rugged handsets with a real push-to-talk key.

The current push-to-talk ring, sized to be pressed with gloves on

Made for a hand that is already full

The ring thickens with your voice, so an operator can see the mic is picking them up over the plant without taking their ear defenders off to check.

  • A large target, distinguishable states, and a caption that does not move between them
  • Rugged handsets with a hardware PTT key are treated as first-class, not as an afterthought
  • Audio plays as it arrives rather than waiting for a recording to finish

Subcontractors, without giving away the site

A subcontractor can be added to the one channel they need for the weeks they are on site, and removed the day they leave.

  • Private channels are per crew; org channels reach the whole organisation
  • Removing someone stops future key grants immediately
  • Every provision, removal and posture change is in the audit trail

When something goes wrong

Emergency on push.tt is a state, not a chime. It persists until somebody clears it, and it overrides Do Not Disturb, Busy and channel mute.

  • Raise, acknowledge and clear are separate — an acknowledgement does not end the alert
  • A worker in distress takes the floor even if someone else is mid-sentence
  • Every raise, acknowledgement and clear is audited, and abuse controls are on by default

Put it on one site

One site, one channel, one week is usually enough to know.
