Phoneboard manages Twilio conference rooms and JK Audio AutoHybrid IP2 devices. This dashboard software was developed for the Global Leadership Network to provide live translation to GLS satellite sites.
l brings up the main controls for phoneboard. Groups of codecs and calls can be controlled with OFF-AIR, Queue, and ON-AIR.
- OFF-AIR - Set all channels to OFF-AIR. This ends any existing codec calls and Twilio conferences. Callers are instructed to redial 15 minutes before the conference.
- Queue - Opens up lines. Callers are prompted for a room to join and placed on hold once the conference starts.
- ON-AIR - Set all channels to ON-AIR. If disconnected, codecs will redial.
There are additional manual controls for phoneboard. These are available for testing individual codec and Twilio API functions. These can be accessed by pressing e.
- Disabled - Disables the watchdog for that channel. The codec is left in its current state.
- OFF AIR - Ends the Twilio conference via the Twilio API and drops the call on the codec.
- ON AIR - Dials the codec and redials once a call is dropped.
- call - Set codec to dial.
- drop - set codec to drop call.
Clicking codec opens the codec management page.
- close - Close conference via Twilio API.
- esc - Reload
- 1...8 - Monitor conference channel
- 0 - End all WebRTC calls
- c - Toggle clocks
- e - Toggle manual controls
- f - Toggle fullscreen
- l - Toggle mastercontrol
Using the Twilio WebRTC API, calls can be monitored within phoneboard. Pressing 1...8 or clicking on the ON-AIR text will dial into the corresponding conference. 🎷 indicates a current WebRTC call.
On mobile devices, clicking Live and Delay dials the conference line for monitoring.
Switchboard is a separate web server that serves TwiML for Twilio. The Twilio service submits data to switchboard via a POST request. TwiML supplied by Switchboard directs Twilio on how to route calls from the JK Audio codecs and phone calls to the DID numbers.
