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.

- TRBOnet Mobile and TRBO.SOS: Configured in Mobile client and TRBO.SOS profiles.
