Telemetry is the message you hear when connecting to or disconnecting from another node and when another node connects or disconnects to your node.
Asterisk/app_rpt sends its telemetry information to all other connected systems through digital (out-of-band, non-audio) data over the VoIP connection. It is purely up to each local system to decide what to do with this information. It can announce it, ignore it or even change the message. The node owner/admin determines what is appropriate for their individual node.
The configuration options mentioned below only apply to what is heard on a specific channel type; out-of-band telemetry is silently forwarded to all other compatible nodes connected in transceive mode.
There are configuration and mode options allowing all telemetry (both local and obtained from other nodes) to be:
- Always announced
- Never announced
- Announced only when a function is locally executed and for short time thereafter
Note: These features document the operation of app_rpt.c version 0.186 or later.
There are 5 telemetry channels which can be individually managed:
