+ * Fires whenever an error occurs when call.js encounters an issue with setting up the call.
+ * <p>
+ * The error given will have a code equal to either `MatrixCall.ERR_LOCAL_OFFER_FAILED` or
+ * `MatrixCall.ERR_NO_USER_MEDIA`. `ERR_LOCAL_OFFER_FAILED` is emitted when the local client
+ * fails to create an offer. `ERR_NO_USER_MEDIA` is emitted when the user has denied access
