A recovery operator may be across the county, under a vehicle or working in gloves beside live traffic. push.tt keeps the whole operation on the same channel anywhere their data connection reaches.
Dispatch can reach one operator or the entire shift without caring which side of town the truck is on. Coverage follows cellular and Wi-Fi rather than a tower at the yard.
The talk target is deliberately large, and rugged Android radios can use their physical push-to-talk paddle. Audio keeps arriving while the screen is off, so the handset can stay clipped to a vest or belt.
Pickup addresses, gate codes, customer names and vehicle details should not be broadcast to anyone with a scanner. Private and organisation channels encrypt them on member devices.
Emergency is a persistent session rather than a chime. It overrides Busy, Solo and channel mute, and remains active until somebody with permission clears it.
push.tt is operational coordination over commercial data networks, not a certified public-safety system. Keep statutory and emergency services on the equipment and procedures required for them.
One dispatcher and a handful of operators is enough to see whether the radios stay on the rack.
