Starting TRBOnet 6.4, you can configure PTT priorities for call participants

  • Higher priority participants can interrupt those with lower priority.
  • Configure settings per participant type (Radios, Mobile Clients, TRBO.SOS, Dispatchers).
  • Default settings can be overridden by individual profiles.
  • Alarm escalation notifications and sign-in/sign-out reminders have fixed interruption behaviors.

Important Notes

  • Does not affect interrupt settings in a radio system. To interrupt Radio calls, both TRBOnet and Radio system must be configured to allow interruption and impolite access.
  • Applies only to half-duplex calls, not applicable to SIP and Full-duplex calls.

Default priority settings

Go to: Dispatch console → Administration → Priority

PTT Priority Configuration Interface
The "PTT Priority configuration" section shows participants/profiles with non-default priorities. Dispatchers without roles and radios with custom profiles are always listed.

Individual priority settings

  • Radios: Set in individual Radio profiles for each subscriber.
  • TRBOnet Mobile and TRBO.SOS: Configured in Mobile client and TRBO.SOS profiles.
  • Dispatchers: Set in Dispatcher account or role settings.
  • Administrator and TRBOnet: Inherits priorities from "PTT Priority Configuration" → "Dispatchers".

Voice Message Quick Command/Task Priorities

  • Emergency and High: Non-interruptible.
  • Low: Interruptible by all other priority levels.
  • Normal: Follows default interruption rules.

Additional Priority Settings

  • Alarm Escalation Notifications: Always interruptible.
  • Sign-in/Sign-out Reminders and RTT Voice Notifications: Non-interruptible by any priority.
  • Single TRBOnet Agent with Multiple Servers: Interruptions processed based on respective priorities.
  • Call Preemption (Capacity Max): Applies when dispatcher and participant have the same priority (+1 added to dispatcher's priority).
