What the detail says

The detail explains the occurrence; it can read, for example:

• WhatsApp could not connect the call. Try again.
• WhatsApp timed out connecting the call. Try again.
• WhatsApp’s call relay could not connect. Try again.

Handling it

An upstream service (such as WhatsApp) failed; retry later or follow the message. Timed out; retry with backoff.
