TelephonyCall.error

This API is available on Firefox OS for internal applications only.

The error read-only property of the TelephonyCall interface indicates a returned error when a call does connect successfully.

This is being obsoleted as of Firefox OS 2.2, as the error messages being returned were confusing (some of the errors aren't actually errors, for example call rejected isn't really an error, just a normal possible outcome) — it is being replaced by the more semantically effective TelephonyCall.disconnectedReason.

Syntax

var myError = myCall.error;

Value

A DOMString.
