Live broadcast
To do an announcement:
- Dial the broadcast number
- A chime signal is heard in all member devices
- As soon as the chime signal is finished the microphone will open (no need to press any PTT button), and the operator can speak
- End the broadcast by pressing the C-key or by replacing the handset
Permissions
By default all users can initiate a broadcast. Often there is a need to set access restrictions, and allow selected users only to initiate broadcast. To configure restrictions navigate to Devices and Connections > Permissions.
Priority handling
If a device receives several broadcasts at the same time, but with different priority, the broadcast with the highest priority will be played out. If the priority is the same, the broadcast which was started first will continue to play.
Broadcasts with priority level 1-20 ("Emergency") will enable Volume & Handset Override on the devices. This is a feature that forces the device to use a second volume setting (e.g. Internal Speaker Override Gain), typically to increase the volume when doing emergency announcements. In case the handset is off-hook, it will reconnect the loudspeaker by forcing the device to go on-hook.
Live broadcast initiated from an integrated system
A live broadcast can be initiated by sending a POST via Zenitel Link. To stop, use DELETE.
POST /api/calls
- form_dirno: Directory number of the device of which the microphone will be used
- to_dirno: Directory number of the target group
- action: setup
DELETE /api/calls
- dirno: Directory number of the device used for the broadcast
Multicast address and port
When a group is configured with the first member, Zenitel Connect Pro assigns a multicast IP-address and a port to that group. This is the address and port that Zenitel devices and Zenitel OEM devices will listen to.
3rd party devices may be able to listen to the same broadcast address and port in order to play the announcement/message. This is however not a supported feature by Zenitel.
