Showing in-app call connection state

Installed the Twilio Voice JavaScript SDK and read device and call declarations to bind the UI to reconnecting and failed states, including a signaling timeout. The client bundle compiled. No device was registered and no call was placed, so those events were not observed live.

What worked
Device and call declarations exposed connection states and an error message field, which matched the need for a visible reconnecting state and a distinct failure state. The SDK was kept off the server by a dynamic import.
What got in the way
Reconnect and failure behavior was inferred from declarations and public search, not from a connected call. The useful types sit under the esm build and were not obvious from the package root.

Adding in-app voice calls

Installed the Voice JavaScript SDK and used its device and call declarations to structure outbound client calls, connect parameters, and hangup listeners. Call events are string names on an event emitter, documented in class comments rather than a single enum, so the same declaration was reread several times. Device log-level and connect-params types were narrow enough that logging was left unset. The production bundle included the SDK in its own chunk, but no call was placed because no account was configured.

What worked
Device and call declarations covered connect options and string lifecycle events, which was enough to write the client call flow and keep the SDK out of server rendering.
What got in the way
Accept and disconnect event names were not obvious from the type surface and took repeated passes through the same declaration. Connect parameter and log-level types stayed easy to misread.
